I just received my package and I go on Sunday for a week. The tickets for the shows are for Aladdin, It's Tough to Be a Bug, and Muppet Vision 3-D. There is a voucher about the size of a half sheet of paper that has three seperate perfrorated vouchers for each of the shows. It says on the voucher to plan to be at the show 30 minutes prior to starting to guarantee a seat.
The Toontown Madness is a paper voucher for each person in the package. I would guess that if I wasn't going to use them I could give them to someone else as they are not numbered or in any way identified to me. Generally Toontown opens to the public an hour after the park itself opens.
For example if Disneyland opens at 9:00 a.m. then Toontown wouldn't open until 10:00 a.m. If you have a Toontown Madness ticket then you could go there right away at 9:00 a.m. I guess there is some sort of ceremony and photo op but since I haven't done it yet I'm not sure.
I booked my package through AAA so I also got special luggage tags for the 50th, pins with Tinkerbell and the castle for the 50th, a commemorative photo of Walt from the first day, a voucher for a 50th anniversary crystal frame once I get there, a voucher for a free 5 x 7 photo of me with the characters to put in the new frame, a voucher for a pin and lanyard - basically just lots of little extras that I'm pretty excited about -- plus getting the unlimited fastpass should be pretty cool!
