Caster is not easily adjustable and only necessary for straight-line drag cars. It helps drag cars stay straight.
Camber and toe-in [or out] should be zero for general running. Slight camber and front toe-in will aid cars tight handling, a little.
Rear toe-in should always be zero. You may check these settings with a ruler.

Good luck with all this I hope I have been helpful. There are many ways of doing things and my suggestions I can only hope are good.
