Personally, I'd cough up the dough for the lower grill and lamp assemblies. It may run you $500, but if they'll pay for the facia paint, and install, thats a freakin bargain. Buy them on your own and bring them to the body shop! Re-use your old grill for now. You can always upgrade that to something else later. While your at it, see if they'll paint it when they paint the facia. You'll also need a new belly pan and inner fenderwells, but they're cheap. Get it done, or you'll regret it later.
