I'd recommend going to
http://www.touringplans.com and getting a plan for each day. Based upon your objectives (kids/adults/arrival time/etc), it'll give you a print out of the sequence to go to attractions. This results in shorter waiting times and allows you to see more than people who go in without a plan. Another great message board to learn about all things disney is
http://www.disboards.com. You can get all kinds of tips for the parks, resorts, transportation, dining, you name it.
Crowd-wise, you should be in pretty good shape though. My wife and I went the same week last year and it was pretty slow. We got on virtually everything with no more than a 20 minute wait. You'll want to utilize fast passes for attractions like Toy Story Mania(the best ride @ Disney right now), Soarin, Test Track, and a handful of others.
Hopefully your weather is better than ours was: 8 days/7 nights of 93-94 degree sun. It was 3 showers/day for us. If you're on the Disney Dining Plan, hopefully you've made all of your dinner reservations. My favorite restaurants:
Le Cellier, Germany, Chef Mickeys, Crystal Palace, Boma(breakfast and dinner), and 50's Prime Time Cafe are just a few.
