I have the guide and its pretty good. If you are concerned about changes in the interface between the current version when the book was written and the present version then you can install the version that comes w/ the book. (Or downlaod it from blender.org) Lately I have just been picking away at online tutorials. The Wiki online book mentioned above was very good as well. The help menu in v 2.37a (and I assume earlier versions) will lead you to a lot of good stuff on the web.
