UPDATE:

I have to add another book to the list. This one was written by two very good friends of mine: Greg Rewis and Stephanie Sullivan. Though I haven’t read it yet because they haven’t sent me a copy (*ahem*) I know it has to be an excellent resource for anyone working with CSS. Greg taught me almost everything I know about Evangelism as he and I have traveled all over the world together since 2000 talking about Dreamweaver, Flash, AIR, and other Macromedia/Adobe tools. He knows more about Dreamweaver than anybody I know. Stef is an expert in all things CSS, HTML, web standards, etc.
