whirlwind pvm barb help

just a couple of notable questions..keep in mind, i'm PVM. I want to do strong dmg, have an okay BO, and still be able to survive with enough leech. IAS would also be plus but i prefer dmg: 1) what should i socket inside my upgraded arreats and ss. Some ppl say um rune. Other say 40ed jewels? 2) is it better to use eth botd cb + ss, or to duel-wield 2x eth botd cb's? 3) might merc? holy freeze? 4) should i go for all warcry charms, masteries charms, or a mix of both? 5) strength/dex pts - enough to wear items, then the rest in vita? 6) should i have a second attack besides ww (ex: for bosses or physical immune) 7) max iron skin? 8) could sum1 also post a basic skill distribution thanks!

(bump) please...any1..help

i say eth botd and ss

and if u dont have max resist then put a um, but if u have near max just get some charms or upgrade natural resist,

i say might merc,

i say mix of both charms,

str-enough for items, dex-enough for max block,

other attack get berserk(verystrong and good for physical immune),

from what i heard dont max iron skin max shout

max ww,bo,sword mastery, then some into berserk and max shout and the rest just some points into iron skin, fast run walk, and natural resistance, with the +skills from items they should be decent

15 points into sword mastery is just as good, so i would put 10 points into it, maxed everything u need to max out and then later put as many points as u want into it.
