Swerve Encoder and Wiring Questions

[TheHolyHades1]

Hi. I'm working on a design for a swerve drive robot, and, as this is my first attempt at actually making one, I've got a couple questions.

1. What precision is generally suggested for the encoders on the steering motor? We've currently got a 24 turn encoder which can be geared. I'm thinking we should try to gear it so that we get roughly 360 degree precision, but I have no idea if that's under/overkill.

2. How have people previously solved the issue of power wires for a module with the motor orientations similar to this: http://www.chiefdelphi.com/media/photos/33335

Thanks!

EDIT: Some additional information:

Also, this robot will be done at a small scale, roughly 1' x 1' chassis, as this is going to be more of a code/control experiment than a mechanical system experiment.
