In honesty, dual-wield only really works effectively at really high gear levels. If you're still trying to progress through Acts 2 & 3, sword & board + enchantress is the way to go. Pick up a shield with 8-10% crit chance, high block % and high block value and it's very comparable damage to DW at moderate gear levels (in that you loose very little dps, if any, for significant survivability gains). Your gear should more than easily be able to clear Acts 2 & 3. Some packs in Act 3/4 can be horror (demonic tremors *shudder*), even with great gear, but most are doable. My gear when I cleared Act 4 was very comparable.
Unless your dps is suitably high and you're at the point where you can farm Act 3, then Mantra of Evasion + Hard Target is the way to go, rather than Mantra of Conviction + Overawe. Conviction is great when you're at the point when you can farm, but it's not great for progression and if you're still dieing a lot (I'm not sure what mantra you're using, just thought it worth making the point as your armour is low).
I'm personally a fan of double spirit generator builds, swapping Blind (in the 'standard' [blind, serenity, breath, fot, sweeping wind, mantra] build) for Deadly Reach - Foresight, and using that coupled with FoT - Thunderclap. Foresight is a modest dps increase, and while DR is generally less dps and less loh than FoT, it's very useful for keeping sweeping winds up when kiting, dps'ing while moving out of ground effects, at range, through waller walls and so on. That + FoT for your main damage & the teleport, the combination feels very versitile.
