Help me spend my last passive points

I am currently level 63. I need some direction for my next 15-25 points.

Right now I am dual wielding maces, mostly because I dont have a good 2 hander, but i like dual wield. Is dual wielding maces even an end game option? Or must i choose 2hander?
For skills, i am mostly ground slam and heavy strike, with LoH, added fire dmg, faster attacks, and added physical dmg gems.

My thoughts on passive direction:
--pick up three passives for ele resistance (15% each fire/light/cold)
--possibly spend 6 points to get to Celestial Walker in the mage tree
--add some dual wield passives if dual wield is viable
--add more mace damage passives (2hand if i must go two hand)
--add some attack speed passives (i like attack speed)
--or should i head for another cluster of life passives? (current hp is 3k with gear, my gear sucks)

What would you all suggest for passive direction?
