The real advantage to gearing is you keep the motor turning so you don't stall it out. The same principle with a car, you have the same torque and horsepower in every gear but unless you car is really REALLY powerful you have to reduce it so you don't stall out until you get into higher into the power band. Hope this helps some.

No, you get very different torques by gearing it differently. Torque is basically an angular force. Gears are basically like levers; depending how they work (ie larger or smaller gear than the one before it) they either increase or decrease your torque. They also, inversely to torque, decrease or increase your speed. Now, as far as voltage fits in, voltage can change the amount of speed and torque. But usually when we do speed/torque calculations we assume a maximum voltage as that is where the motor is most efficient and gives the best results.
