Will this fit over my factory bumper structure, or do I need to remove the original?

This cover installs over the existing factory bumper beam and mounting brackets. You'll retain the original support structure; the new cover simply replaces the outer plastic skin.

Are the fog light cutouts pre-drilled?

The fog light openings are molded as part of the cover design. You'll need to confirm alignment with your factory wiring and ducting during test-fit before final installation.

Should I paint this before or after bolting it on?

Most installers prefer to paint off the vehicle to avoid overspray and ensure even coverage. Prime and base-coat the cover before final mounting to the brackets.
