If your car is bone stock, you should start out with an intake, then exhaust and header. Those 3 should be the main things you start with when modding a car (unless you plan on going FI from the beginning). I don't think you will need a fuel rail unless you have a turbo. And I don't think you should get pulleys or cam gears until you have the basic bolt ons. You shouldn't do those two unless you know which route your going.
