By the sounds of it you have a caster problem, not camber.

Basically (by the sounds of it) your right hand front caster bush is shagged which allows your front wheel to move backwards which causes your rubbing issue plus it basically makes the wheel base on the right side shorter than the left, hence it pulls to the left.
Replace your caster rod bushes and your problems will most likely be fixed. Replace with nolathane for lastability and tightness or with rubber for softer feel.
