How much current does the motor require? Could it be powered with an arduino or would I need a separate motor controller?

For light loads 1/8-1/4A but can spike to 850mA if you try to stall it. Even at 3V, though the RPM's will be lower these motors have decent amount of torque. Probably best for ~5V applications, at 12V they scream. And likely best with a PWM controller, especially at higher voltages.

I can see two threaded holes on the same side as the shaft. What are the size of the Screws that fit the holes?

They will be metric. Most of these little motors use a 2.6 mm screw.

What’s the best way to make the shaft adhere to the whee I choose? It’s perfectly smooth and I can’t imagine it do anything but spinning in place.

You could grind a bit of a flat along the shaft. Then a set screw or for light duty, just some glue should drive it.
