Last year the parade began at the front of the park, from gates on the left hand side, just past Sid's, went up the main drag, hooked a left at the hat, in front of the ABC theater and Sounds Dangerous, and went through the gate to the left of Star Tours/Jedi Training Stage. This is the route of the regular parade too.
Fastpasses for the celebrity autographs are handed out at the beginning of the day....people usually head there first...I don't know if they are wristbands, or regular fast passes, but they go fast. We skip this, although we may do it this year to meet Rick McCallum as he is a pretty big deal! As for the autograph books that are Star Wars specific, I've never seen them...although it may be cute to get a kids Star Wars picture book and have them autograph in there....I've seen some that have minimal words...just an idea!!
I hope you have a great time, I know I'm incredibly excited...I can barely stand to be at work!!! (Although, that is most of the time.)
Have fun!
