The cover of tail light can be repaired or replaced. I think that inner side of the light is safe..
About the boot(diggie) see if dry denting is possible or leave it as it is if your car is in genuine condition.. Because in Pakistan rusted and faded paint genuine car's are preferred at the time of resale instead of touched upp or freahly painted car's...
Bumper can also be repaired easily. And only that part can be re-sprayed.
