There are adequate wiring diagrams in the PM752 driver manual from Zapp. The breakout board will make it easy - you basically connect a wire from each output, to the driver and another wire from the driver back to ground.

Stepper motors, again look at the datasheet for the diagram which shows you the wire colours and work it out from there. If once you've connected the motor to the driver, and with nothing powered up, the motor is harder to turn then the motor is wired wrong so check it as that would probably break the driver. That's about all that could go wrong...

Let me know if you need more info.
