Ok serious Reply:
For ubers you want to use Gface, massive CB takes bosses down quickly and you can even use goblin toes or gore riders for more CB (50+ is ez).
For general MFing you will want to use Ik helm with 35+ mf roll, with 2x Ptopaz you will get 80+mf easily.
Your most important slot is the weapon. If you really got nothing then obedience is a great choice in an elite polearm (massive CB, 20+ all res, very high ED). I use an eBotd warpike and it has everything a barb needs.
For MFing I use IK helm, Skullders armor, chance guards, Aldur's boots, goldwrap, 34 mf 20 all res amu, raven frost, dual res ar life dual leech ring and eBotd war pike
