with steppers you need minimum 2 * the listed voltage, preferably more
You first stepper is listed as 12v, minimum you need 24v. The current rating is fine for a pololu A4988
The second stepper is also says its 12v but it you multiply the resistance 2.3 by the current 1.5 you get 3.45v also fine for a A4988 (this is good for a 12v system)
Any standard reprap drivers will work on both of these, if you supply enough voltage.
