Stack as much dodge, parry, and mastery as possible. Mastery primarily is your best stat, get as much of it as you can. Most of your gems should be mastery/ stamina.
Tailoring is a completely useless profession for tanking, if you can I'd recommend getting jewelcrafting, engineering, mining, blacksmithing, or leatherworking. All provide pretty decent benefits for a tank, leatherworking probably the most so.
Stamina trinkets are not that good, try to get trinkets with a lot of mastery or parry or dodge.
You can talent out of seals of the pure and hallowed ground, neither talent is of much use to you as a tank. You want to also take 1 point out of reckoning. Place those talents into pursuit of justice and judgements of the just and maxing out rule of law.
Switch glyph of consecrate for glyph of lay on hands, reducing the cooldown on a very powerful tanking CD is incredibly useful, and you use consecrate very rarely now, and in the situations where you do use it, you want to cast it more often, not have it last longer.
Replace glyph of crusader strike with glyph of word of glory, word of glory is an amazing ability, use it any time your hp drops below 70% (if you have 3 holy power.)
You want the mastery enchant on gloves, not expertise. And put mending on your weapon for now.
For the actual heroics, remember glyph of holy wrath, the aoe stun is very useful. In throne of tides on the first boss, you need to save avenger's shield as an interrupt for shock blast, remember hammer of justice is also an interrupt. You also need to save interrupts for the first boss in shadowfang keep. totalhalibut's channel on youtube has good informational videos for learning the heroics also.
