3pt8 turbo

a few days ago i posted that i was hit while parked in a parking lot of a movie theater, now i need to know where how severe my damage is. in the beginning i thought it was just as simple as changing my front bumper but after now i am scared that i might have internal damage. can anyone please advise me on what types of internal damage might of been caused? the bumper is shifted inwards so the headlights are actually alittle bit in front of the bumper. they no longer line up correctly and on the left side of the bumper, its actually hanging off the car by alittle bit as well. do you guys think i might need some new bumper guards or anything? any other damage i should check for? hopefully all i need to do is pickup a new front bumper. TIA
