If you want a good day with minimal waits, hit Superman, Big Dipper, and Mind Eraser early. Then, if you want, you can go on Mr. Hyde's Nasty Fall, which is an Intamin 1st gen freefall.
From there, I would head over to Villain. Batman and Serial Thriller build up crazy lines early, but die way down (Thriller can have a 45 minute wait at noon, and be a walk on at 5)
The Wildlife side offers a great 3-D movie, "Pirates 4-D" (yes, 4-D) with Leslie Nielsen. It is great.
Other than that, enjoy your day, the park has improved a lot.
