Looks great ! Black on white combo gives it a race edge, have you got black alloys?
Whatever you do though don't go for a black bonnet in fear of being taken for a taxi ! We have taxis round here that are white and they seem to have black bonnets and roofs?
Branding I guess.
No just the standard monza shadows fitted

Can you wax a wrap?
Guy that fitted the wrap put a polish over the top of it which just looked like autoglym srp if my eyes didn't deceive me, the wrap is actually better quality than I thought, just as glossy as my recently sprayed diffuser but I suppose time will tell on how it holds up
