For that your parts would be 1 solid state relay to turn motor ON/OFF and
1 electromechanical 4PDT relay motor direction UP/DOWN (2 Poles) and the
other 2 poles to jump the limit switches (UP jumps down L/S and DOWN jumps
up L/S). Or if you have and would prefer to use 4 SSR's that should work
great too.

Will a basic stamp power a 4PDT relay coil directly? I haven't checked, but
I assume it won't. If it will, do you set up the controller to sink the
relay? Or can it also source?

Specs are on their website. You'll need drive transistors to operate
relays. Someone suggested TIP120, a good suggestion. Holler if you
want some help with that.
