Yes, I just bought the chip, it was around $4.50. You will also need an adapter if you are breadboarding. The chip is available in two packages, so get the appropriate adapter.
As for the motor, I am modifying another product, so I was stuck with what was in it. It is a 12v, 0.75A, 400 step, 6 wire motor. Being that it is 6 wire, it can be used as a unipolar or bipolar motor.
