Most barbs tend to go for axes for a start due to the superiority to the swords, i.e lower requirements, like dex and str, higher dmg same ranges, as the swords and the fact that alot more runewords can be made in axes.
If ur pvm i personally think shield is a waste and rather use 2 weaps or a 2 hander, unless OFC ur making a Conc Barb.
Pvm wise the best weap combos are;
botd + botd
botd + beast
grief + beast
the reason why grief + beast is last in this is due to lack of leech and the fact that the weaps will break fast.
Botd is a common choice due to the good dmg and high leech not as high dmg as Grief + Beast but makes up for it in leech and mods.
Grief + Beast
Botd + beast
As here dmg is more important and leech is useless in pvp where as OW+ DS is the key in pvp.
Death + Beast or Death + Grief are good combos. But if you're going with weapon/shield I'd go with Death and Ber'd stormshield. As for skills, it all depends on what kind of barb you want. Some more insight into this would help us help you a little better.
