My favorite book on this is APE by Guy Kawasaki.

APE stands for "Author, Publisher, Entrepreneur" and I always felt like he made the process really approachable.

In my opinion, there were one or two sections of the book that got a little too nitty gritty (like literally giving click-by-click instructions for certain steps).

But overall, if you're looking for one great book to just orient yourself, this is it.

Thanks! I've found a book by Guy Kawasaki called APE that discusses self publishing. http://www.amazon.com/APE-Author-Publisher-Entrepreneur-How-... He references OP's book as an example. I love when things cycle back on themselves like that.
