Oh, hold on to your hat gchiker. The book I'm talking about is The Unofficial Guide to Walt Disney World 2005. I just picked it up at Barnes and Noble. It is jam packed full of great info for WDW.
A friend loaned me an older version when I first went to WDW 3 years ago---it's where I learned to be one of those theme park commando moms---up early and off to the parks, fanny packs strapped onto the kids, ride list in hand. I don't remember floor plans in that edition though, so this new book was such a wonderful surprise for me.
