Have never tried to enchant aaulets, boots, belts, or rings. And what you can do to armor seems to be very little, remove the move penalty via anvil and improve the armor value with scale scraps oh and add steakth with void essence, so far thats all I have found but there may be thingsI dont know about.

Yeah tormented soul is weird, in one playthrough I had about 5 of em at one point and one on the weapon, this playthrough I have seen one in 12 levels? WTF?

I feel your pain man!
