Q: What is the torque setting for my crank bolts?
A: For Isis, the initial installation may require up to 60 foot-pounds (ft-lbs.). Subsequent tightening should be at 35 ft-lbs. For square taper systems, the initial and subsequent tightening should be done at 35 ft-lbs. Remember to grease your spindle in both instances.

I've always put a light coat on mine. (And I do mean LIGHT) Never had a problem.
Various bike part torque specs
I've greased/not greased my square tapers and I can't tell any difference. I usually just put a film of grease on them.
From Park Tools:
Aluminum cranks typically do not require lubrication of this press fit. Aluminum by its nature is self-lubricating as it is covered with a thin layer of oxidation. Adequate torque is typically enough to keep arms from creaking.
