I'd say head to Medusa first then Batman the ride since their the most popular rides and longest waits.The Chiller gets long too. When we were there they stated running the other side after the line got. I imangine that would be best for later in the day. When we were there it was a rainy Wednsday so lines were pretty short except for the 3 I mentioned above. GASM is my favorite Arrow looper now that the Phantom is no more. The back seat is incredible on the first drop. A little headbanging but nothing like the Chiller or Phantom. It really rips thru the boomerang and two corkscrews near the end. If you never did Houdidnis Great Escape it a fun ride and should be tried at least once.
For food the have a McDonalds near the back of the park. We ate at an Italian place near the Ferris Wheel, Laser Tag. Basicly between Chiller and Wheel though. They have good Chicken Parmesan Subs and Hot Sausage.
There was a discount shop (I think near the water show area) that had discounted shirts. I picked up a cool GASM T for like 7 bucks.
I don't know where you could find any discont tickets. I guess you can try local fast foodand conveience stores. I think it's around $45 to get in and $8 to park.
Have fun!
