Am I correct in assuming that the motor turns full on when the pot value is less then the joystick and doesn't turn off until after it goes past?

You can set up a PID Loop to control the overshoot even if you are only bringing it to one position. A quick search of CD will give you a lot of information. Basically you are going to take the difference between the value of the joystick and the potentiometer to set the speed of the motor (needs to be on a speed controller of course).
