I would recommend picking up a few copies of Airbrush Action magazine. It's got a lot of good information on what airbrushes are best suited for different purposes, as well as how-to's and tons of other information.
I would also recommend the book Automotive Cheaptricks and SFX by Craig Fraser. It's mainly focused on automotive airbrushing, but can be useful for anyone that wants to get into airbrushing.
Good luck!
