I second the recommendation on The Unoffical Guide to Disney World. Its one of the best travel books around, and can really save you loads of waiting on line time, not to mention money.

As for hotels, its not clear what your budget is. I tend to skip the on-site hotels - they are consistently overpriced, and the free transportation lure is somewhat of a scam - generally you can get to the parks faster, or just as fast from many off-site, but nearby properties. How much do you want to spend on the hotel?
