I've actually found that sacrificing camber for caster helps out more. My caster is maxed out, with camber relatively mild. It also helps to not slam the car, to keep in the better portion of the camber curve.

As far as tips go: slow in and fast out will help prevent "understeer". Many novices try to brake too deep into corners, often mistaking understeer as simply asking too much from the front tires (turning and braking too much at the same time). Keep smooth, and keep your head up (pay attention to the course a few cones/ gates ahead of you), and you'll do fine.

Other than that, tire pressures will vary greatly depending on what tires you run. One novice trick is to use chalk to mark the edge of your tire, and see how far down the shoulder you're wearing. If your tire rolls too much (lots of chalk is worn away), raise pressures. If you're not wearing the shoulder at all, drop pressures a bit.
