Will these interfere with my jack points if I need to lift the car?

Side skirts mount at the rocker panel area where most drivers never jack. Check your service manual for exact jack point location on your model year — if you use a scissor jack or floor jack under the center frame rails or front/rear subframe, you'll have full clearance.

Do I need to prep or paint these before bolting them on?

They ship in matte black ready to install. If your paint has any chips or you want a seamless blend with your body color, light scuff and mask before spraying — but out of the box, they're good to bolt.

What hardware do I need to secure them?

Mounting hardware is not included with the skirts themselves. You'll use the factory mounting points, so source stainless bolts and clips that match your OEM hardware spec — your dealer or service manual will confirm the exact size.
