Powering stepper motors

Hi! I recently bought two Nema 17 stepper motors from the shop along with the Adafruit DC & stepper motor HAT for a rpi-based project. I’m new to electronics and have no idea how to power this thing, so looking for some help. What I’m wondering is this:

1. Is the Adafruit HAT the right thing for connecting the two Nema 17s to a rpi zero?
2. What kind of power supply do I need?
3. Googling around, I read something about heatsinks possibly being needed for the driver, does this apply to my situation?

Have a nice day! :)
