Will this bumper cover my fog light cutouts, or do I need to modify it?

Dry-fit the bumper first to verify alignment with your fog lights. If cutouts don't line up perfectly, you may need to trim or enlarge them slightly — test-fit before committing to any cuts.

Does this cover up my bumper sensors or do I need to create openings?

Sensor hole placement isn't specified — check where your factory sensors sit before final installation. You may need to cut or drill sensor access holes to match your vehicle's setup.

What should I do to prepare this bumper before painting?

Sand the surface with appropriate grit to promote paint adhesion, then clean thoroughly to remove dust. Apply primer and your final color coat according to your paint system's specifications.
