You've worked out all the kinks from my initial review I think.

What gkathellar said, except I'd just have Force Attunement be always on, and allow light armor.


plus:
Is Projected Blow damage + str, or +wis?

Is Force Manipulation a SLA or Psionic Ability?

Fists of Force are slam attacks, doesn't that make them natural weapons and thus not eligible for TWF? (I guess this is easily handwaved)

I still suggest a flying augmentation, where you step on the palm of the fist, and treat it like a magic carpet
