Body/Soul blessing and Body/soul Deity are buffs that you can give to your party, that stay after you switch to 2hand.
A skill that increases your attack is basicly the passive needed to get 2hand skills ^^ you should just get all the 2hand passives and skills.
Ofcource you should also get sprint assault and skins atleast.
And if you plan on party grinding fences / screens / protect / howling shout are nice aswell

If you're going to pvp a lot, i suggest getting axe aswell, and only knockback from 1hand ^^
and @ Blinxx, i mentioned holy spell, holy recovery is nice if you like to pvp, healing orbit is nice for party play, actualy heals less hp and costs way more mp.
I myself plan to go robes on last tier d10 btw, im light armor atm, and int's just hit to hard on me, while i can basicly take any str there is.
