so...… my first question is, do you have adjustable tension rods in the front?
2* difference in caster SHOULD cause a noticeable pull in that direction.
if you plan on drifting, you want a "bent" type tension rod
like these ones from PBM

If you dgaf about drifting, a straight tension rod will be fine

you also said your rear toe is fucked up? might need adjustable toe arms in the rear, and whenever you get coilovers and lower an s-chassis, you'll need adjustable RUCAs as well.
once you've got these things, THEN, get an alignment and they should be able to bring you back within a reasonable spec.
