A P only loop makes sense in this application, because there is so much physical damping/resistance in the yaw of a robot; there is no need for a software dampening. The navX is likely much more dependable than the wheels for determining orientation, that I would not use drive train encoders in the navigation loop, but ONLY to to feed the wheel/motor PID loop.

As far as color, if you insist on the right color, you'd need a new piece (or two) of carpet each year.
