Buy Actionscript the Definitive Guide by Colin Moock...it is THE book....also look for Samuel Wan and Branden Halls new book ( http://www.amazon.com/exec/obidos/tg...15862?v=glance ). Colin Moocks book is for Flash 5, but still is the best one out there. He is coming out with one for MX, but I am not sure when it is due out.
