Help w/ Barb.

I am building my first Barb. I am stuck as what to do with it. I am currently level 72 with 63 skill points left to use. I have basic points into some things but masteries are empty. I dint know what the best mastery is to use.
My Weapons I HAve Currently Are:
-2 Litesabre
-IKs Maul
-Ariocs Needle
-2 Glimshed Axes(I think I spelled it wronG)
I do not know what mastery to go with and whether or not to max double swing, berserk, or ww.
Also, how do you refill axes after you throw them.
Thank YOU- The dumb Newb
