Rallye wheel accessories

Okay, just took delivery of my new Rallye's. They are 15's with Large bolt pattern. And now the fun begins...
1. I need trim rings. 2 different size wheels, 7's and 8's. I REALLY would prefer brushed. Does anybody have knowledge on where to find some AND if polished are easiest to find, HAS ANYONE EVER DARED TO TRY BRUSHING THEM THEMSELVES? Yeah, I know it may be a reach.
2. Center caps, I need the later "acorn" style (which I find the description odd, because I think the earlier ones more resemble and acorn) and was wondering where I could find them reasonably priced. Not crazy about the idea of the later ones with plugs.
3. Probably the easiest query, I need lugs; input on original style, price and quality.
Thanks gents and any ladies that may be out there...
