Re: Gear pitch?
Will the gearbox be used for the drivetrain? If so, and if the motors and robots are anything like years past, 20 pitch seems to be the norm, and 3/8" face width is acceptable as long as you can keep your tolerances.  On the first stage reduction on the small CIMs, you can go with 32 pitch if you want. Make sure they are all steel except in one very special circumstance 
Also, a lot of gears come with big heavy hubs. In most cases, don't be afraid to reduce their width and or diamteter, or even eliminatate them altogether.
