Just about to get an SV2

and wanted some advice as to what else I need to buy with it.
E.G. brass weights, tyres, hop-ups, pinion, shock oils, springs, etc.
Also some advice on build/set-up.
E.G. diff high/low, shocks front or back, front arms swapped?, etc.
Will be running mostly at Silverstone club night. Indoor on astroturf. Running a Novak 7.5L with saddles.
