I assume you are not staying onsite. You've got the right plan.
The key is arriving early, the parking garage opens at 8am and a line of cars forms at 07:45am.
Your plan is perfect, just see Shrek when you arrive to USF. Don't worry about a fast pass for it.
Next ride the Mummy, if you really like it, and think you want to do it in the afternoon, get a fast pass now, otherwise, head over to IOA. The Mummy has a single rider line, so you may want to use that later.
Head left and ride Hulk. If you really like it, get a fast pass for noon. If you already got a fastpass from the Mummy, you won't be able to do this.
Spiderman (could user single rider line, but it can be long).
Dr. Doom (again, use single rider line)
Dueling Dragons
JPRA
Rip Saw Falls
Popeye
You may want to skip Rip Saw Falls and Popeye because you will get wet and it's not fun walking around a park, hot, sweaty, with wet cloths.
Head back to USF and do the shows. Use single rider line for MIB. Use your fastpass for the Mummy if you got one. BTTF will make you sick, it's one of those simulators that tricks your brain.
