It's true that you should have as little contact with the ball as possible, but you still need some minimum amount of contact, otherwise you won't impart much energy to it. Many teams seem to have found that 1-2" of pinch on the ball will work well.
With a 6" wheel you could be looking for 2,000-5,000rpm axle speed, depending on what range you want. the actual ratio will depend on what motor(s) you're using.
