I suppose you could put opto-isolators on the limit switch inputs and the coast/brake.
Potentiometers, however, I would expect to be noise-resistant. You could still put a op-amp inline if you want.

Use the capacitors as a part of a filter or as bypass for frequencies that should not be there. After all a potentiometer and limit switch should be pretty constant as you've said.
