What alignment adjustments are possible and to what extent on a stock s13?

you wont be able to align your car to those specs with stock adjustments.

iirc, only the hicas equipped 240sx had a rear toe adjustment. there is no stock camber/caster adjustment on the front or rear of the 240sx, only front toe.

in order to have all camber/caster/toe angles adjustable, you need the following:
tension rods (for front caster adjustment)
camber plates (for front camber adjustment)

rear upper control arms (for rear camber adjustment)
rear toe arms (for rear toe adjustment)

this is the minimum you need, you could go more indepth with adjustble traction rods and adjustable control arms, but i feel for the type of driving you are doing you will not need those.
