Hi there,
I don't know if this will help or not, but, I make Shutterfly books too. I am not sure if you want to do just basic photo books with the elements Shutterfly gives you or you like to digiscrap. I do both and I find that Mousecrappers.com is a Disney digiscrappers dream! It is chocked full of inspiration. I usually digiscrap our Disney vacations and use Shutterfly elements given for my more general photo books for the year. I do remember that Shutterfly used to have a gallery you could tag your books and also search for books via tags. That would be sad if they didn't have any more.
