I work at Knotts (games department) and am a frequent visitor :) so here is my advice:
Yes, I agree Ghostrider should be the first ride of the day. Next head for Log Ride if you are a fan of that type, or even if you are not. The lines will get long throughout the day, and this is your best chance. From there, the Boardwalk is right around the corner. So go on Boomerang, Hammerhead. Don't worry about Perilous Plunge. THe line is always very short. You can do it any time during the day, besides you probably don't want to get that wet so early anyway.
If you are a dark ride fan, visit Kingdom of the Dinosaurs. The line WILL get long later. just take my word for it. I mean over an hour long! I suggest heading back towards fiesta village, and on your way go on supreme scream.
Next, head for Montezoomas Revenge, then Jaguar.
You should not have to worry much about lines for the fiesta village flat rides, so do those at your convinience.
Don't miss the Calico Mine Ride. it is great!
Be sure and visit Mystery Lodge and the Wild West Stunt Show. Both are well done shows. that is pretty much the entire park, have fun!!
