Unless the tabs of the headlight are broken/bent or there are deep scratches, the headlight likely will just need a bit of wet sanding and polishing. The other bonus is that if the paint work is done well, the new paint may match your car better than the original bumper's paint.
Good luck, I was cut off by an illegal immigrant with no license or insurance, ended up rear ending him, and I was 100% at fault regardless. He never even filed a claim for his car and strongly discouraged me from calling the cops when I noticed his license, registration, and "insurance" were all under different names even when he claimed it was all for him.
