I'm pretty unfamiliar with carburetors, what should I look for to see what kinda shape it's in?

Well usually you dont want one that is leaking gas all over the place, thats a big problem. A carburetor in poor condition can cause vacuum leaks, bad performance and bad mileage. If it idles smooth, is not leaking and smoothly accelerates I would just leave it alone.
Dont be afraid to tear into a carb, I have blindly rebuilt 3 of them in recent years and they worked fine. Head down to the parts store and get a big can of carb dip you can drop the carb in to clean everything before disassembly. Also write down any numbers you find stamped on the carb and take them to the parts store so they can get you the right kit.I always work on carbs on a bath towel so I dont lose the little bb's and springs. With everything apart you just make sure everything is clean and replace the little parts that came with the kit, adjust floats, blow out passages and assemble everything back together. I almost forgot to mention that before you take ANYTHING apart take a ton of pictures of everything so you dont mix up vacuum lines and linkage when you go to put it back together.
If you want to get really serious about carb work find a book store and look for literature, it does not even have to be specific to your carb. If you go for it and run into a snag dont be afraid to post on here.
