Hmmm, depending on the exact showtimes and your arrival time, I'd suggest Safari, Pangani, Lion King and Bugs Life.
Safari can have long wait times and supposedly the animals are more mobile in the morning. Pangani is right next to the exit so it's very easy to explore post-ride. Lion King seats several hundred people so as long as you arrive 30 minutes before showtime you should get a good seat. Usually there's an 11:15am showtime we go to. Bug's Life runs near continuous and makes a relaxing queue to go through (as you descend around the Tree of Life).
Do Safari first. There is less of a wait, you can see more animals, and they are more active. Right after that, do Pangani. It is close to the exit of the safari. Have fun on your trip!!!
If the wait for Safari is already long, see about fastpasses... if they're not up too late you can get them and head back to FotLK for the first show there (it's always less crowded). You definitely want to do the Safari early... that priority #1. ITtbaB can be saved for any time when you want to get indoors. And it can be FP'd. We usually do Pangani trail whenever we get off of the Safari.
