The headlight bezels or chrome rings are hooked in at the top and secured by a single screw at the bottom. There is a set of clips that goes inside the headlight ring. They serve to hold the rubber gasket in place and also the top clip has a tang that slides into a slot in the top of the headlight pot.
It also sounds like your hood hinges are worn out. Look at the pivot holes in the hinge. If they are distorted and enlarged then they are worn out.
