Mathieu Fontaine has just posted an excellent tutorial and guide for using an airbrush on miniatures. He covers everything from types of airbrushes to troubleshooting problems. Check it out here: Akaranseth Tutorials.
We've also got a whole series of articles on using an airbrush, with several videos.
I'm using my airbrush to base coat and put the first shades and highlights on my Fire Hawks. It is a great time-saver!
