Well, your mauler build looks fine. However, the throwing build needs 14 wpf per point of power throw. So, 14*7=98. Even if that is true, I would go with much more as with ranged items you can see the difference in damage and accuracy a bit more than melee can with speed and damage.

This one is a bit more on track with 21/15. You will have to sacrifice the ironflesh to be fully effective, but you could take out 1 shield point and put it in IF, but not needed or very beneficial.
Here's 18/18, a bit less damage but faster and therefore more versatile.
