Resistances are VERY useful if you want to do Ubers later, something a WW Barb is very good at. Your priorities should be resistances and armor, though the move speed buff is very handy if you won't be using an Enigma.
Spend your remaining points on your passives page.
You also want one point in Battle Command and Berserk (for dealing with physical immunes). Put all your skill points in WW, Axe Mastery, Battle Orders and Shout. You do not need perfects, but you need the items. You're going to need good items to beat Hell solo.
