Here are the factory specs, look at the '76 C3 column or the '84 SC/RS column



Row height is 108+/-5 f and 12+/-5 rear, I run my C3 a little lower than the SC/RS height, ie @ 149/3,, you want a little rake to the car and use a rack spacer from ~120 down(remember 120 is lower than 108 and 145 is lower still)

front;
toe: 0 pressed is good, pressed means that the leading edge of the tire is under a separating force as when driven, relaxed toe will be a bit of toe in. For A/X toe out is often used to speed turn in, some guys run track w/ this but it makes the car darty in daily use.
camber: 0° to -10' is stock but up to 1° is fine and it gives some extra tire room at the lip, for track use you want as much as can be gotten, but camber plates are then necessary
get as much caster as you can, often it's not possible to get to the spec, the more caster the more feel you will get through the steering wheel.

rear;
you need some toe in for stability 10' is fine
camber you want ~ 1° more than whats used in front, again you additionally get tire room at the lips
