I have discovered after a lengthly flick through most of the Office books at "Borders" that the missing manuals books are very good. I have purchased Access 2007 and Project 2007 to start with and these say on the front :
"The book that should have been in the box". This is true, it's got a wealth of useful extras, background help, interesting utilities that I have not come across in other manuals. they are written in a nice relaxed style, brave enough to even say when a facility is rubbish or never took off.
Check them out ...
The Access 2007 book covers macros, VB, SQL ,all the basic Objects and Database theory as well.
