RR, toe is done last. caster, camber, then recheck caster. you will probably have to go back and forth with both until you get it as good as you can get it, as adjusting one will affect the other to some degree. add or adjust what you want to compensate for road crown. then do your toe, as toe doesn't affect either, but it's possible the others will affect toe, especially if caster is way off, because the lower balljoint will raise and lower the outer tierod connection. think bump steer.
that is the way i do it. your mileage may vary.
