I suggest buying the book they sell at several Disney gift shops called "Hidden Mickeys". I know they have it in the sundries shop at the Contemporary. It's set up like a scavenger hunt, but you don't have to complete it that way if you don't want to. It's not a complete list (I don't think there is such thing as a complete list), but it's the best list I've seen yet. I believe it was about $12 if I remember correctly.
