Your question: How do you reverse the direction of a stepper motor?

To change direction you need to reverse the current in one set of coils only. At the moment the two motors are connected in parallel and turn in the same direction. Swap ONE of the coil pairs over and you should be able to get the two motors turn in the opposite direction with the same drive signal.
