Yes all RSV's come with intercoms but not the headsets or cables. Front plug in should be on your tank left of the tank bib. The rear is also on left side but since mine has been triked for a couple of years I've forgotten just where the plug is.
Mirrors, go to different suppliers such as Dennis Kirk, J. C. Whitney, etc. and pick out a pair that suits you. Just remember they have to be metric thread and reverse threads on the one side.
For driving lights it's personal preference, Barry's suggestion is a good one.
Suppliers, Yamaha Star accessories, Kuryakyn, Show Chrome, Diamond R (one of my favorites), Fleabay, etc...
PS welcome aboard!!!
