Total cost of the parts plus tax:
$777.37
So, with the paint job for the unpainted bumper cover and labor, it is about $1,000 at the minimum. My insurance deductible is $500.
It should be as good as new if they match the color. I will still have to wax it.
I hope they check the calibration of the ultrasound parking sensors and blind-spot monitor radar as well. The latter is probably fine, and I think the former are fine, too.
