The obvious ones you've named
There's a film about Walt Disney's life but I can't for the life of me remember the name.
I know there is a lot of work going on at HS so I'm not sure if all of these will be available on your visit.
Epcot:
Soarin
Test Track
Mission Space
Spending some time in each country is always good fun and what I knew as Kim Possible was exciting it makes you feel like such a big kid!
The parades and fireworks are fantastic in all the parks, so make sure you save some time for them!
I'm sure I've forgotten some as its been a few years since my last visit, but I love Disney and there is certainly enough in each park to warrant a visit. I think the Disney experience is unlike any other park, and you'll feel 10 years younger
