Personally, I completely ignore Finesse and still manage to have ~2k or so. It seems to be "enough". At least, I'm noticing a lot of skills getting BPE'd. I think it's more important for LMs and Burgs, who need to apply debuff effects reliably whether acting in a CC or DPS role, than us.
As for Tact Mit, 50% is plenty for a non-tank.
