I'd say search!
1) No. Not slickly or easily anyway. FM transmitter, tape adaptor or Tape deck hack. Or new HU!
2) Personal preference. Toyo T1R, Falken FK 452 and Michellin PS2s are highly rated.
3) Personal Preference. Silkolene, Amsoil etc etc. Loads of info on oil from opie on here.
4) CS or EPRacing are your best best. Various finishes available (colour coded, half carbon, full carbon.....)
That saved you a few searches.......
by the way!
