what about volts? How many for the motors I listed above?

Depends on the driver. With Geckos, for each motor you need 2/3 the rated current for a single phase. 2.8*.666 = 1.86a/motor. For geckos. Xylotex is similar. I'm assuming Automation Direct is as well, that's why they sell the low current supply. You never know, though.
Volts is a different story. Most motors have a rated voltage. You want to normally run several times that voltage, depending on the application. Some people will tell you 10 to 20 times the rated voltage. More voltage gives you higher speeds. It also gives you hotter motors. The best advice I've heard is to run just enough volts to give you the speed you want. Figuring this out can be tricky. The Xylotex makes it easy. Realistic 28-30V max, which should be fine for just about any motor.
And whether you use 1 or 3 motors, volts stays the same.
