ban bot motor? err... 
Yes, teams typically get 2 FP motors.
What sized wheel?
How fast do you want to go?
Divide the circumference of the wheel by 85% of the motors free speed (a rough approximation for full speed under load) then multiply by the gear ratio (1:15 reduction would mean multiplying by 1/15th) and there's your top speed.
Generally 5ft/s is a good pusher robot, 8ft/s is quick with good acceleration, and 11ft/s is FAST with moderate acceleration.
