I highly recommend NOT reading the W3C spec to start out if you actually want to get anywhere. Just dive in and start coding, CSS isn't really all that hard.

I found it really useful/fun to just copy another site (e.g. Facebook or Digg) to get a hang of how things work. If you get stuck you can always take a look at their CSS using Firebug or by opening up their stylesheet in the browser.
