Welcome to TalkBass CharlieOW.
The tuners and knobs are pretty generic, so no problem getting gold plated ones, but the bridge is a bit trickier, since black and chrome are the standards.
I do remember seeing some good old "oil rig" aftermarket bridges in gold, but Hipshot Supertone would be my choice if I needed a bridge swap.
Contrary to the common information available, I for one haven't had any problems with the classic 3 point bridge.
The gold covers will be more of a hassle, either You have to grind the PU sides down to allow the cover to fit, or you have to get the plastic plated/painted.
