A 12X2 would be it takes the armeture 12 rotations in the can to make the rear wheels to turn 360 deg 2 times if I remember correctly.
As far as motors go I would strongly suggest looking into a 19t, they are very strong motors and will give you good run time on some 3600's most likely a little over 6 1/2 min depending on how old the cells are and how many times the have been cycled.
For gearing if you just went and picked up a 18, 19 and 20 tooth pinion gear you should be set for just about anything, as far as bashin with it the motor wont be a silly fast one but it will be a safe good reliable motor that you wont have to worry about the brush going bad after 25 runs or so and the arm will stay nice and tru.
