Steve smith has a great book out on mini sprint set up. That more than anything else will get you pointed in the right direction.

We use blocks to get our baseline set up before every race, they also set the ride height to start out with (can't do both). From there we adjust the car with our t-bar stops and front spring nuts to move the weight around and to adjust for track conditions. Loose for hot laps and tighter as the track goes from tacky to slick.

Mike Dicey over at "HYPER RACING" also wrote some pretty good stuff on chassis set up.
