Personally, I strongly recommend trauling through the W3 site and copying out their tables for CSS - I made a word document of around 9 pages when I first started so that I could have an on hand reference ....
....then I went and made a little document with "Tips & Tricks" and everytime I found a useful method, or notes on how to overcome a problem, I would try it, and when I got it workig and think I understood it, would write it up and print it out.... I got around 16 Tips & Tricks within 3 weeks - and I printed them out too.
If you play around, you may find different ways to do things - the darn thing about CSS is alot of thefixes or techniques are reliant upon what is already in place... so sometimes a clever bit ofcodewon't work for you due to previous properties.
So, once you hae a technique or method you like that seems to work on multiple browsers.... make a note of it in a word doc etc.... and keep it (date it too

).
