For Actionscript: Essential Actionscript 3.0 by Colin Moock is a great book. There's also a book on Actionscript Design Patterns that is okay. For Flex: I used Total Training's DVD training and then just used Adobe's docs. Total Training also has a new online training option that is cheaper than buying the DVDs. I'd recommend the online library if you have a high-speed connection and don't mind NOT being able to download the vids. (You can get online access to ALL Adobe training products for about the same as one or two Flex DVDs, roughly $200. I just gave away and sold a bunch of access codes to the online library, and everyone reported they were thrilled with the training and service. I've just used the DVDs.) Send me an email if you're interested in buying any Total Training DVDs...I have a bunch of new ones still in the shrinkwrap and some that were opened and viewed once. I'm out of the online access codes, though.
