Since hit is your goal,
Put +10 hit/+15 sta in your helm and a +10 Agility/+15 sta in your belt's red socket.
You'll 'lose' 6 sta from the belt but 'gain' 12 sta from the helm for a total gain of +6 sta plus 10 hit.
Can you work on grinding ~3500 gold to buy the 5 primordials you'll need for Boots of Kingly Upheval, which have hit on them and are a EH upgrade? You can sell the ores you farm to level your mining up to 450 for the full 60 sta bonus, plus should net you the eternal earths plus mats for titansteel you need for the boots.
That will net you 53 hit. That coupled with rep ring at 277 for another 3 hit, will, probably within 2 weeks (you can gain 400g a day easily from Ice Crown/Dalaran/JC dailies) will bump you up to 116 hit. You're a space goat, so there's another 1% hit, so you're getting close to taunt miss-immune at this point without sacrificing your frosties on a sub-optimal EH frosty upgrade.
I'm sure others will have suggestions on other things, that this should address your main concern, hit. At 116, you're probably really close to very comfortable with taunt-misses (threat probably isn't much of an issue and if it is, hit is the least effective way to increase it).
