2000 Camry bumper

My Camry was wrecked in the front and I wanted to go out and buy a front bumper and grill. How do I go about taking the old bumper/ grill off ? Also my drivers side headlight is loose... was there any clamps or bolts holding it in and if there was, where are they located?

You have to be careful doing this as deployment of the airbag is possible.Disconnect the negative battery cable, disconnect the positive battery cable and wait a few minutes.Detach the screws holding the top,bottom,and sides of the bumper cover.(Use a small screwdriver to pop the center button up on the plastic fasteners,but do not remove.They stay in the ferrules.Remove the cover.There are retaining bolts holding the headlight housing in,remove the light to access these.
