Posts of this nature should really go in the HALP! forum.
For the record you should only go for +12 stam bonuses if it only requires one hybrid gem (like in your helm). If you gem for +12 stam bonuses in a piece that requires 1 blue, 1 red, and 1 yellow is like gemming for 2 +6 stam bonuses and results in a loss of 18 stam. So the gems in your legs and BP should be all +30 stam gems. Of course then you lose your meta gem requirement. I'd say put the dodge/stam gem in your belt until you get a piece with a better +stam socket bonus.
I would also personally gem def/stam in that helm since you have lots of hit already. I'd also enchant your gloves with either 18 stam or 240 armor.
Otherwise looks good to me.
