good planning so far.
I would say paint the mirrors too match. as far as the grill, i'm not a fan of chrome, but it does flow well with the lights as is. I would say if you're thinking of painting the grill (body or black would look good) then open the headlights and paint them as well. already been opened once for the restro so what's one more time.
Another thought; how about getting the coupe bumpers?
I saw the Eibach springs, but are you doing the pro kit or sportlines? also do you plan on doing dampers and alignment parts? since the pro kit is just over an inch drop you can prolly get away with just stock toe adjustment in the rear, but the sportlines will need more adjustment than that to keep them from eating your tires. they also will detroy the stock dampers pretty quick as well.
