But I'm having trouble googling up any comprehensible equations to see if that would allow for the station to be tidally-locked to the sun.
That's easy. No, by definition it can't be tidally locked. A tidally locked objects rotates once per year, and this object rotates a bit more than once per hour. There are no stable solutions for 'spinning around an axis that is pointed at the sun'.

If you want it to not wobble a lot, it's pointing along the same axis as its orbiting.
