I would shoot for 2-6 degrees positive caster. The more the better but keep in mind the more you have the harder it will be to turn. 2-3 would be fine on the street. You probably aren't going to get any more than that with stock arms.
On camber, I would shoot for 0 to -1 degree , the more negative the better the car will take corners at the expense of inner edge wear. For toe, I would go for 1/16" - 1/8" toe in. These are ballpark numbers.
