For the most part, that's a pretty good plan. The best coasters to start off with are definitely Flight Deck, Time Warp, The Bat, Fly, Thunder Run, SkyRider, and Back Lot Stunt Coaster. These usually get real long lines real quick. Out of all of them Flight Deck and Time Warp are probably the best to tackle first. Behemoth and Dragon Fyre have very high capacities so the waits aren't usually that long, even though it might look as if they are. The Bat (having only one train) has a very low capacity, as well as The Fly and Thunder Run. I wouldn't be too worried about Vortex, it says that the wait is 60 minutes with the queues full but I found that it was much shorter than that, though it's been a while since I've been on And SkyRider is among one of the worst capacity rides in the park, it says that it's a 60 minute wait from the front, but I'd think that it's more like 2-2 1/2 hours with how slow loading is.
Behemoth, Minebuster and Wilde Beast all have great to so-so capacities, so you should probably do those later on. By the evening lines do start dieing down, for example yesterday at around 8:30 PM Behemoth was around a 10 minute wait, and Drop Tower was a walk on. As it gets later the existence of lines is very miminal- though with the crowds getting heavier each week, it might be different by next week, hopefully not though
