Since you're going to be there for 4 days, I'd start out by riding the smaller coasters and then work my my way up. (smaller meaning Raptor, Mantis, Mean Streak, Magnum :))
If it is mid-day in August, the crowds may be big, but it will help that it's a Thursday. If you start riding coasters at noon, I'd think you could get all the coasters in by that night...maybe. I'd skip Disaster Transport, Wildcat, Woodstock Express for the first day if you can't get them all in. You should definitely end the day with MF. The lift colors are awesome and dropping 300 ft into pitch blackness is just incredible...beyond words incredible.
