Gear/Sprocket Help

I work mainly on electrical and programming so if I say anything absurd you'll know why...

We (team 506) had alot of trouble with our drive system this year. We used those new chiaphua motors and had them continually stopping and starting after pushing a goal a few feet. We replaced our sprocket on the wheel with a much larger one (5-6in dia) and were then able to push much more powerfully without the motors stopping on us. Since we don't have alot of engineering help and we have no shop type classes we have designed most of our systems by trial and error, which is not the ideal way to do it. I was wondering if any teams had tips, equations, etc to help us figure out what the gear ratio should be for a given motor, especially when the motor is to be used as a drive motor (i think its use makes a difference, not sure how much).

Thanks in advance, and good luck to all of you.
