Need some advice please

I've been unholy dps since day 1 that I rolled this toon. I've never really been interested in tanking before but have since amassed enough gear to start tanking heroics. Now it's been almost a week and I'm finding that I want to improve.

Here's my armory link: http://www.armory-light.com/us/Anetheron/Jal/#

I know I need to enchant/gem some items. I'm planning:

boots: 22 stamina
legs: 55 stamina/22 agility
bracers: 40 stamina

I'm just wondering which gems to put in bracers and gloves and should I be concerned about the socket bonuses?

Overall is my character adequately geared for heroics? I'm finding that I'm a bit squishy in some of the ICC heroics. Many people look at my gs and leave without giving it a go.

Socket for pure stamina with the gear you have. If you running low on defense gem stamina/defense in yellow socket, and in red socket either expertise/stamina (of you're really low) or agi/stamina (for some dodge and armor).
Only gem for socketbonus to for fill the meta and if the stamina bonus is good, like +9 stamina.

Consider Stamina and runspeed on boots instead for 22 stamina. There are loads of fights its better then the extra 7 stamina you get.
Same, consider hp on chest instead of 10 stats.
When you stop struggle with treat, change to either 18 stamina or 240 armor on gloves.

That should be it i guess.
