The black-gold combo is a great look, always reminds me of John Player Specials race paint schemes. A mate is fitting gold parts to his White/blue R6 and the main thing he's found is that not all gold is the same....so take your time sourcing parts so that they match.
The 'less is more' quote springs to mind so for instance I'd do gold pazzo levers with black reservior caps and gold chain with black rear sprocket.
Definitely wouldn't do all fixings / rearsets etc- I'd change most to black and then pick a few gold highlights.
Are you thinking of powdercoating the wheels gold? Sure I saw a picture of one on ducatisti.co.uk. Looked great.
Alternatively.....someone posted some images in the superbike pictures thread of their dark with just a handfull of red parts. Lovely!!
