Its hard to be specific without knowing a heap more about it, but getting the right tyres will be 90% of getting it right. A lot of guys swear by Pits (search the tread for the different part numbers), while personally I tend to alternate between Ride or TRG depending on the grip level. If you are using foams again it's just a case of getting the right balance - I'd start with a soft rear and a hard front, with a med front available if I needed more front grip.
After that I'd focus on ride height and bump control. I'd probably start around a 6mm ride height with maybe 1-1.5mm droop on the rear and similar ride height at the front, maybe 0.5mm lower. Also use something like Tamiya AW grease or similar on the front pins to help damp the front springs. I use a Tamiya Flouro Yellow spring on the pitch shock with about 50Wt oil, but that would only be a starting point. The roll damper has 60Wt oil.
After that its about tuning the car to suit you.
