2. Make a priority seating at a character meal or two. (We like the Crystal Palace and Chef Mickey's).
3. Look at the height restrictions for each ride/attraction.
Fantasyland should be fine for all the kids. Your 5 and 8 yr olds may like Space Mountain , Splash Mountain, Buzz LIghtyear. The shows in MGM are great. Definitely do the Animal Kingdom safari. My advice is to check out all the rides/attractions on this site and the official Disney site. Decide with your kids which things are important to see.
Try to remember that you can't possibly do everything and not to stress yourself trying. Enjoy the things you do get to do and you can plan on the way home for your next trip Have a great time!
