Reddit mentions of SanDisk Ultra 16GB Class 10 SDHC Memory Card Up To 40MB/s- SDSDUN-0016G-G46 [Older Version]

Yeah, that is a really good idea, probably going to order some class 4 cards. Super cheap but infinitely valuable.

Edit: Damn 16GB class 10 cards for $6.84

Ok is this a good memory card??

How much memory do you think i'll need for photos and can you recommend a good bag?

TLDR: just get the camera. And a memory card.

You don't need any of those things to take pictures. I would expect your teacher to tell you to throw most of that crap away as it will actively prevent you from taking good pictures. Pretty much the only thing in that bundle that will help you take good pictures is the lens hood, and even that only helps in certain situations (bright light, like the sun, shining onto the lens from the side and causing flare if you have dust on your lens). A couple of the cleaning supplies are nice to have, and some people swear by those center-pinch lens caps, but I'd suggest using your camera for a few weeks first and then buying the accessories you find that you need.

If you're buying the camera new, there should be a Nikon-branded shoulder strap in the box. Use that for a little while then if there's something about it you don't like (such as the big yellow "NIKON" splashed across it ;)), buy a strap that fixes that for you. Bags are a whole 'nother thread topic, people get really passionate about their bags. I'm from the school that considers the bag an obstacle to shooting: if you have to open it up first, you're not going to bother to take the camera out to take a shot. If your car's a mess and your camera's going to be bouncing around a lot on the way to class, though, you can get a small one to securely hold your camera, but if you can you should go to a store and pick one out in person so you can literally try it on (put it on your shoulder and make sure it fits well) before buying.

Oh you'll probably need to get an SD card, too. Probably something in the 8-16 GB range. Don't spend too much time stressing over finding the right card (that's another rabbit-hole you can go down with lots of people really passionate about minor differences in write or read speeds that really won't affect you), just buy a reasonably-priced (i.e. not the cheapest) one, preferably from a major brand. SanDisk is usually good.
