You should look into some of the Expanded Universe books, it gets pretty interesting. Even wonder boy Luke gets hitched, and Leia and Han have some children.
We've got this old one that I think my brother has in his dorm right now, but it's probably from the nineties but definitely before Phantom Menace. It actually says that Darth Vader became disfigured after a fight on a volcanic planet (err, I've forgotten it's name). I remember when my brother told me that I imagined Darth Vader in a lei with some hula girls, partying on the rim of a volcano when one pushed him over.
