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

Well the best weapons u have are the gimmershed so i would max double swing, put some points into double throw and max throw mastery, other wise put points into sword mastery, ww, and zerk.

Refilling any throwable weapon just requires a repair.

Do NOT MAX DOUBLE SWING.

Do NOT use throwing weps unless you want to PvP exclusively.

I'd suggest going towards an IK barb, maxing mace mastery, concentrate, and as many synergies you can get your hands on.
