Problem here is the model and it's rariety, there was someone on Ebay a while ago selling a full kit for your bike, might be worth checking there first. Most of the standard kit you'll be able to find on Ebay I'd imagine, some stuff like indicators aren't worth bartering over, may as well just buy new for what they cost.
It's the panels etc that will be the hard ones to find, you could get the exiting ones repaired I'd imagine, find yourself a decent painter and go and see what he says before you get sold new panels you don't necessarily need to buy.
