Removing the headlight ass'y is considerably easier with a late model C3 due to the removable lower valance panel. Best bet is to put the car up on jackstands and remove lt lower valance panel, spoilers, and grill/turn signal ass'y. This should open up the the area around the headlight ass'y to be removed. I would suggest placing a piece of cardboard across the A/C condenser to help protect it from from accidental damage. You should be able to remove the vacuum lines and then the four bolts that hold the headlight mounting bracket to the header bar and nose reinforcement bar. The headlight ass'y should drop down and out. Two people will help drop the ass'y and set it back in easier.
