Wipe your seats down with some mild soap water once in a while.. They get dirty easily but are very easy to clean as well. You will suffer with fabric seats.
Never done it before, but it should involve tapping to the +12V Signal Light line, and the other wire to a chassis grounding point right? This will probably void your wiring warranty, something you should avoid since there are plenty of electronic things that can fail or give problems in this car, not to mention that you have to find a point to drag the wire through the chassis which may cause water leakage into your car.
