I want to use this to reset my stat/ability points.
By doing so, does it set everything back to 0 and give's me back the refunded stat points in game? Or does this program only let me change the numerical values?
It will only let you change the values, but the is an option to set unspent points in the character tab.
So you could either edit only the values you want or clear everything and assign unspent points.
