Roy, this is my first carburetor rebuild, but when I got my Holley carb, my brother-in-law (who has restored cars before) gave me this book:

The most important thing (i think) for a beginner, is that you don't wanna get something that needs a total restoration. Get something that you can tinker on and still drive. Otherwise it's not as fun. It'll just sit there. Remember, you can get a lot of satisfaction out of just doing simple stuff for the car you already have. You'll save A LOT of money doing routine maintenance on your own car, and you'll feel proud to drive it... I promise. Every time you stop fast after you change your break pads, you'll think, "I did that."
If you want a cheap easy car to learn on... get any rear-wheel-drive car without fuel injection from like... 1950 - 1985. A bigger car with a smaller engine will give you more room to work with. The less "power" options you get (power breaks, power windows, etc.), the easier it'll be.
It really is a personal thing, though. I'd have to know more details about what you wanted, in order to suggest something more specific. Personally, I would get a truck without fuel injection from the early eighties that hasn't spent much time just sitting. The newer it is, the less time it's had to deteriorate. And when cars sit, they rot.
I have some experience doing little repairs here and there... I've read a lot about it, and I watch those how-to car shows on the weekends. EXPERIENCE IS THE BEST TEACHER. You don't really know how to do something 'til you've screwed it up a couple times.
ONE MORE THING!!! If you wanna know how an internal combustion engine works without dropping the cash on a real whole car, they make some really awesome working models that are clear so you can see the moving parts:

I put one of those together in middle school. It was a blast!
They call me Dollar Bill 'cause I always make sense.
