There's a couple attack plans, one that involves only the thrill rides. But since you've never been, just do all the rides in order going clockwise.
The parking garage opens at 8am, try to be there at that time. Walk to the gate of IOA and get in line. If you are first in the park, you can take a lap of walk on rides with no wait. This is the biggest tip I can give you. At 11am, the crowds arrive and the park is packed. If you are in the park when it opens, you'll be ahead of the crowd for one lap.
Hulk (Front row, then back row)
Spiderman
Dr. Doom
Continue clockwise. If you don't care about getting wet, ride Rip Saw Falls and Popeye now, otherwise you come back later, but the lines will be longer. You can ride JPRA in the back and only get a little splash.
Leave a change of cloths in the car or a $5 locker up front. On Popeye, put your shoes in the middle compartment and keep your feet up. It's the socks you want to keep dry. If you don't want to get wet then you skip Popeye and Rip Saw Falls, but they are great rides.
