I have a hood if you want..Its off an 03 (not that it matters its 2nd gen)
Its painted white, and has very light hardly noticable hail damage. Make me an offer if your interested
It looks like you make contact with your bumper so thats good news.
Your frame should be fine.
Id try to goto a junk yard and rip out the coresupport, headlights, radiator (might be better to get a new one) and a hood.
As long as your fenders didnt get hit it should be relativly easy fix.
damn man yours looks worse than mine i tboned a guy that did a illegal uturn wasnt my fault. was this one your fault? i had all gm replacement parts done to mine except the hood had a goodmark cowl hood done. if you use new parts plan on about 3000
