Generally speaking, your problem is mostly lack of enchants, but I'll try to cover everything I see needing improvement.
As for enchants, your gear is not enchanted with optimal enchants I'm afraid.
Here is a list of what I recommend:
For
head slot -
Glyph of the Defender you can buy this at the Cavern of Time when you are revered with the Keepers of time.
For
shoulder slot - seeing as you are Aldor your options are
Inscription of Warding which you already have, and at exalted can be upgraded to
Greater Inscription of Warding.
For
cloak slot -
12 defense if defense is needed (it's better to use this enchant for that than gem for it),
12 agility for dodge and crit or
120 armor for the armor. Armor is probably the best option here, though I'm not 100% sure, it IS the cheapest :).
For
chest slot -
150 health is your best bet, though if defense is needed
15 defense is also an option, tad better than gemming for defense, as 1 stamina=1 defense rating on gems, but with Vitalty maxed 1 stamina=10.5 health, on this enchant you gain 10 health for 1 defense rating.
For
bracer slot -
12 stamina is the best bet, but with the option to get
12 defense instead, if needed.
For
glove slot -
2% threat is the only real option here.
For
leg slot -
Clefthide Leg Armor is the economic version, while
Nethercleft Leg Armor is the best one.
For
boot slot -
Boar's Speed though very expensive,
12 stamina should do if you lack the money (or don't want to spend so much on an item you think you'll replace.
For
weapon slot -
Mongoose is THE option, as expensive as it is. Can be skipped if you think your weapon will be replaced soon.
For
shield slot -
18 shield block rate for extra threat, but only when you feel comfortable with your health (which sadly you still shouldn't). Or the one you are using now
18 stamina.
Heavy Knothide Armor Kit and
Knothide Armor Kit can replace any slot (where applicable) if you think it'll take you too long a time to get the enchant itself, but only for that time, it's never the best option.
As for gems, you go for strength, agility and defense rating quite alot it seems.
Strength and agility are not really needed as a Warrior tank, so it's best to gem for something else.
You also gem for every gem bonus, that's not optimal as some of the gem bonuses are really not helpful for you, the shoulder, chest and bracers should be ignored. Some of the more helpful gem bonus can be ignored as well for more stamina if you think you lack in it.
I agree with fromanthebarbarian about
Solid Star of Elune being your best bet on gems, but if the bonus from gemming correct is desireable try to use:
For
yellow slots -
Rigid Dawnstone,
Thick Dawnstone or
Enduring Talasite. The first will help with threat generation and the next 2 are good for reaching the defense minimum (which you are past).
For
red slots -
Subtle Living Ruby or
Flashling Living Ruby both offer avoidance, while the former gives more avoidance and the latter more threat generation.
For
blue slots -
Solid Star of Elune should be your ONLY choice. It's the default gem to put when you don't need the socket bonus.
For
meta slots, when you get one -
Eternal Earthstorm Diamond is a very solid choice, more block value equals more threat from Shield Slam, also the best option to reach defense minimum if you need to gem for it in my opinion, the other option is
Powerful Earthstorm Diamond which is great if you are over 490 defense.
Most of your gear is OK, but some items really stick to the eye:
Your ranged weapon is for DPS, better options are
Gyro-Balanced Khorium Destroyer but is very expensive or
Nightstrike from Priestess Delrissa from The Magisters Terrace, both normal and heroic. She is the "5vs5" boss.
The Boomstick is good as well, though it's from Anzu in Heroic Sethekk Halls, he is the summonable boss.
As for trinkets, your
Runed Fungalcap needs to be replaced, aim for
Argussian Compass from heroic Underbog, but before that
Adamantie Figurine from the Shadow Labyrinth (normal) could solve your need to gem for defense.
Your belt can be replaced (keep it for times you need arcane resistance, like in the Magister's Terrace second boss) for something more generic like
Sha'tari Vindicator's Waistguard which you gain by doing a chain of quests in Netherstorm, this is the quest for the key to Arcatraz.
As for your spec, it seems quite solid, I'd take out the points from Improved Shield Bash and Improved Revenge and put them into Focused Rage and Improved Thunderclap, I think the damage reduction from improving Thunderclap (add to that the extra threat generated and reduced cost) outweights the damage reduction from stunning the mobs with Improved Revenge (which doesn't work against bosses, unlike Thunderclap), and Improving Shield Bash is quite pointless as most mobs stop casting after you bash their casts.
The point in Ubridled Wrath can better serve you in Improved Demoralizing Roar or Improved Bloodrage in my opinion.
All in all you have quite a good start there, I suggest you try out some of the suggestion people will give you in this threat and then you can decide for yourself what is best for you, do this while practicing on tanking normals, as I don't think your numbers cut it for heroics yet, though soon they will. I imagine regemming and reenchanting will take you there.
As a general note, you have quite alot of resilience, even holding a trinket for it and gemming to get more of it (the bracer gem bonus), resilience offers very little to you, while it's inevitable you get it from PvP items, you should avoid it on the rest of your gear, the damage reduction to DoTs is quite small in comparison of what you could be getting, and you should be crit immune anyhow.
The numbers I'd aim for, if you want to start heroics are ~12.5K health, crit immune (for heroics only 485 defense is needed, for raids 490), 30% dodge+parry at the very least. Your armor seems decent enough.
Once you start heroics, upgrades will come from everywhere, you have SO many ways to spend your badges it's quite sick (badge gear is THAT good). Try to earn a few more from doing the SSO dailies (are they still up? My paytime expired when the isle was roughly 1 month old).
Have fun, and hope I helped a little,
Yuval.
