Well, the best barb,weapon's wise, is either a lance or sword. Since good lances are hard to come by, I suggest sword.
Now, your main skills are:
Whirlwind
Sword Mastery
Shout(defence)
Battle Orders(Life,Stamina,Mana)
BS(+1 to all skills)
Something Resist(Forgot what it's called. Basically improoves resitence)
Your sword will, most likely be two-handed, so a Shield is out of the question. Get some high-defence armor(700+).
Your boots and gloves had best be something with good resistence. For amy's, I suggest a +2 to barb skills, and 2 soj's for rings.
But, for starting equip, I suggest using Sig set. Pretty common set nowadays, so shouldn't be too hard.
I'm sorry I don't know more, but I'm a zon pro. Not a barb pro.
