For beginners up to advanced/expert stuff? like a complete training course?
I don’t think there’s a book that covers everything from beginners to experts…
I would start with a beginner book, then an expert one. To be specific, I don’t really now 
Ive read about six different books on Flash and AS now. My favorites would have to be the training from the source books as well as Flash advanced by Russell Chun. Skip the beginner stuff and go straight to the advanced. Your head will hurt for a bit, but you’ll get over it. 
Ultimately the best sources for learning Ive found are forums like this and downloading fla’s to dig through and see what makes them tick.
You should try ActionScript for Flash MX: The Definitive Guide (Second Edition) by Colin Moock. Check it out at moock.org
Hope that helps
