I would suggest doing an expected torque calculation (just ask if you need help) for turning the wheel, and then seeing what kind of speeds that you can get using candidate motors using that. I know it is kind of backwards, but it may be an easier and better approach, because you may say "I want 150 RPM" and the only way you can get that is to use FP motors--which you might not want to dedicate to the drive train. So get an idea of what motors you'd want to dedicate, then run the numbers with them to see how fast you can turn the wheels at appropriate current levels, and then choose the speed. Obviously you will want it at a certain speed or above. From my experience, Globe motors and Window motors are fairly appropriate for this task, but you should calculate it with other motors just to be sure you don't want to use them. I would personally be wary of investing my FP's or Banebots RS-550 into the drivetrain--the rest of the robot usually needs some oomph, too.
