Get a pi 3, because integrated wifi + bluetooth.

I would suggest that you buy a good quality power supply (Canakit is good, else the official rpi one). Just don't use chinese crap or a phone charger.

Also, get a good SD card. I strongly suggest a Samsung Evo+ 16GB bought from a reputable seller.

A breakout board of this type can be useful (albeit not essential at all)

I personally bought a kit from Canakit including the previously mentionned stuff. It's a good kit, but not necessarily a great value. The SD card they include is good but not great, and I didn't like the case.

Then for everything electronics, Aliexpress and Ebay are your new best friends. You'll find the same stuff on Amazon, but you'll end up paying 2-3x the price. I cannot suggest a kit of electronic components, because it is a bit ridiculous to just buy 30 resistors. Get 600 of them for 5$ instead.

Edit: here is a copy of a previous answer I've given to a similar question.

Basic Power supply. You probably already have a 5v wall wart, check if it can supply 2.5A. If it came with a product you bought, it's decent quality. If you need to buy one, get it from Element 14 or an other reputable store. You can find cheaper ones, but I strongly advise against getting a random Chinese psu. Doing so would be asking for trouble.

Numerical signal doesn't require high quality cables. This would will do just fine. 3.72 CAD http://www.ebay.ca/itm/6FT-HDMI-1-4-3D-Cable-HDTV-High-Speed-Ethernet-ps3-bluray-1080p-FREE-SHIPPING-/131144973049?hash=item1e88d97af9:g:2gcAAOxyJX1TAj3K

I don't think this is essential at all, but the kit you linked contained one. I bought this one and I'm happy with it. If you want to save some money, I would skip this guy.

Aligator clips. I think 50cm is too long, maybe get 2 sets and shorten the cables of one.

The kit you linked contains 5 resistors. That is a joke. Get this assortment and have fun sorting them.

Jumpers. Essential to connect stuff to the pi. $2.84 http://www.aliexpress.com/item/Dupont-line-120pcs-20cm-male-to-male-male-to-female-and-female-to-female-jumper-wire/1490773403.html
More jumpers. Those are for connecting stuff on a breadboard. I don't really like those as your board will get messy quickly, but at least this kit contains shorter jumpers than the previous one, so it's a nice addition. I would suggest you get 6 colors x 25m of 22 AWG SOLID CORE wire. You can cut it to length and make your own jumpers. I got a kit from Elenco for about 20$ on Amazon. If you want to do some breadboarding, I consider than as an essential. $1.38 http://www.aliexpress.com/item/Hot-Sale-65pcs-lot-Jump-Wire-Cable-Male-to-Male-Flexible-Jumper-Wires-for-Arduino-Breadboard/32437796067.html?spm=2114.01010208.3.10.PzcAVY&ws_ab_test=searchweb201556_0,searchweb201602_2_10017_10005_10006_10034_10021_507_10022_10020_10018_10019,searchweb201603_6&btsid=ad849cd3-deff-4e0b-92ae-e3d15373fd4a

Those with 4 leads are a pain in the breadboard. They keep jumping out and stuff. Plus you won't find any use for the extra pair of leads.

Because you won't do breadboarding with your pi all the time. Get a battery connector (next item) to power the board. I suggest you bookmark this shop! Robotdyn is the BEST SHOP on Aliexpress by far. Few items, but very high quality (like, amazing quality and the best packaging I've seen so far). Why not get an arduino nano or uno for a few dollars? Sometimes an arduino is better suited for a project, and they are so cheap.

Cheap cutters, but they cut very well! The only cutters you'll need for a while. $2.14 Wire cutters http://www.ebay.ca/itm/322001218703?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
You'll also need some long nose pliers. Again, no need to get anything fancy.

But if you want to make a gift to yourself, I am absolutely in love with those pliers (make in Italy) http://www.amazon.com/Hakko-PN-2007-Long-Nose-Outside-Serrated/dp/B00FZPHEW2/ref=sr_1_1?s=pc&ie=UTF8&qid=1460924870&sr=8-1&keywords=hakko+pliers

I don't consider a case as an essential. But I love cases. And this one is one of my favorites. It's compatible with the pi3 and because it allows a good airflow, you won't need to add a fan. Just get a "heatsink for rpi" (1$ on Aliexpress) if it doesn't come with your pi.

Nice and cheap kit, but by no mean essential for a beginner.

If you get in the hobby of electronics, you'll need some caps. This kit has most values you'll ever need.

Finally, I strongly suggest you get a multimeter. Either get the cheapest one you can find like this one : http://www.amazon.com/General-Hand-held-Multimeter-Transistor-Function/dp/B00066ZZO4/ref=sr_1_6?ie=UTF8&qid=1460925081&sr=8-6&keywords=multimeter (it will do everything you need just fine) or get a Unity UT-61E for about $50. The absolute best meter for the electronic hobbyist, but by no mean required for a beginner. Just don't go in the middle. Don't.

These might be some more "advanced items" but I have found them all to be of extreme usefulness and not too expensive to justify. Note: Where provided Amazon links are for reference only and I have no financial interest in the sale of the item listed.

- A set of ball-tipped metric hex key wrenches. The ball end allows you to get around obstacles and still rotate the fastener. https://www.amazon.com/Bondhus-10946-Balldriver-L-wrenches-1-5-5mm/dp/B0006O4AEC Note: You'll only need, IIRC, three sizes but the set is still cheaper than buying the individual keys.

- A clean popsicle stick works great to "scrape" or swipe the occasional pre-print and post-print drip from a hot nozzle's orifice and cannot damage the metal. Actually a suggested tool by a lot of industrial hot melt adhesive system companies for the reasons I just stated.

- A small open topped container, about the size of a kids sand pail, for all the waste support, brim, raft and skirt material you'll be generating. I happened to have a clean empty plastic 1 gallon OJ jug and cut off the top where the jug started to narrow leaving me a 8" tall "bucket". Small enough to keep next to the machine because tiny bits of PLA...

- A small magnifying glass, good for layer quality inspections.

- A small AA powered penlight, I had one anyway on hand anyway but was surprised at how often I needed it around the printer that it now lives there full time.

- A plastic paint scraper since I do lots of technical prints that leave large amounts of random first layer support spaghetti stuck all over the build plate. https://www.amazon.com/Red-Devil-4718-3-Piece-Plastic/dp/B001SBJIA8 (I know for a fact this set I've linked to is soft enough not to scratch the PEI coating. You actually only want the smallest scraper in the set, the other two can be used for what ever but at $2.99 per set even if you never need the larger ones it's no big loss.)

- A small table-top digital humidity and temperature gauge to monitor your printer's local "micro-climate". At the beginning I found that there was some temp/humidity related print quality issues where I had first set up my printer that forced me to relocate it and the only way I figured that out was by using this gauge. https://www.amazon.com/gp/product/B0013BKDO8/

- Good quality needle nose pliers with some grip to them. The pliers Prusa included with the printer are, IMNSHO, junk. I have both of these and am satisfied with both:
