Refinishing my wheels

[ThatOneEuroE30]

I'm about to refinish my OZ turbo wheels and I want to polish the lip and gold plate the hardware. My question is what can I do to remove minor curb rash and for the bolts should I just go get them gold plated or buy new? I found these on ebay would they work?
