parking lights should be easy. There should be 3 wires coming off the switch if it's a 3 way switch (off, parking, head). There should be a diode between the parking and head lights so you can turn the parking lights on without the headlights, but when you have headlights on both are on.
On the lights themselves, they usually come from the factory with the parking/blinker light tied in with the headlights so you only have to hook up the 1 wire. Just separate that and wire them to the switch separately.
The brake cable holder clips, I just take them off and leave them off. I've never had the brake lines catch or hang up on anything. The lift stretches them pretty good on their own. You will want to readjust the rear brakes after you get the front end lifted up though. Lifting the cart tends to take the rears WAY out of adjustment so you probably won't have any rear brakes. Adjustment should be simple at the proportioning bracket underneath the floorboard, where the rod connects to the cables. Tighten it up so it's "snug" and you'll have rear brakes again
