How is the chain slipping? Is is dropping down or hopping up a rear gear, or is it slipping forward across teeth of the same gear?
Just based on your language, and how I perceive your knowledge of how everything is working, you might be best served by visiting a bike shop. Please don't take that as a knock against you, but if you want to take it in, you will be well served.
That being said, where's the fun in that? Let's do this ourselves!
If the chain is slipping forward, it may be stretched. Check out Sheldon Brown's article on chains. You can measure the chain stretch using a ruler, since every full link (that's two half-links, the individual swiveling parts) is 1" pin-to-pin. Measure twelve inches and the whole 12" should be pin-to-pin on a brand new chain. If your chain is 1/16" past 12" measuring twelve full lengths, replace it. If it gets more gone, it will start wearing down the teeth of your rear gears, and you'll need a new cassette or freewheel, depending on your rear wheel. That will cause slipping and skipping for sure, even with a brand new chain!
If you replace the chain, you will need to get a cheap chain breaker. There are many kinds at different price points, but I can vouch for that one as I carry it with me.
For a new chain, you have to get one that is the right width. This generally depends on the number of rear "speeds" you have. Up to 8 speeds in the rear is a standard chain. 9, 10, and 11 speeds in the rear require a chain that is thinner to fit in between the close spacing between gears.
You can also get a master link and replace a link in your chain with it - you can then remove the chain and reinstall it (for cleaning and work) without using a breaker. That's just a random one I found on amazon, which happens to be for 10-speed chains.
Measure your chain, check your gears for wear. If you have to replace your chain you just need a chain breaker and new parts. If you have to replace the rear gears as well you need a new set of gears and the appropriate freewheel/cassette removal tool. There a few common types of freewheel tools and just one cassette removal tool. They lock in to splines and allow you to use a standard wrench or socket to remove the tool.
EDIT:
Here's a video about removing a cassette

So, bit of an update, this is what I ordered earlier and wanting to make sure they're compatible/good choices:
Cassette:
SRAM PG850 8 Speed
Rear Derailleur
Shimano Alvio 8 Speed
Chain
SRAM 850
and I was unable to find any 'cheap' single bar end shifters, most were the 'extreme' kind that have bars extended out in front of the rider(unsure what that is called); however, was able to find a 'good' deal for a right Shimano Sora ST3000 8 Speed shifters.
From my understanding, I could mix/match many of the parts except the RD and the sifter should be the same brand. They all should be 8 speed?
The one part that I have reservations about is the rear deraileur as I would prefer something more 'roady' than the Alivio but unable to find any that are '8 speed'; would it be possible to get a 9 speed Shimano RD and have it still function well?
great looking bike! shimano 600 components of that era (so-called "tri-color") has quite a good reputation and cult following.
as far as a frame ID: i would suggest heading over to bikeforum's classic and vintage, there are a few peugeot threads there and an impressive amount of knowledge on the forum.
chain-- width only changed with the advent of 9-speed, so you can use any "8-speed" chain just fine. personally i love the sram chains with power-link because they are good-quality, inexpensive, and the link makes installing and removing very easy (e.g. for cleaning the chain off the bike).

I haven't personally used that model, but i've been using sram chains for years. They have a superior linking system to other manufacturers. If you buy or borrow a chain breaker, installing it yourself is simple enough. The big detail that you want to shop for is an 8 speed chain.
