Bear Mitigation
All that follows assumes:
Level 70 vs Level 73 mob
Base Bear form hp of 12000
Tauren Druid
3/3 Thick Hide
5/5 Heart of the Wild
3/3 Survival of the Fittest
Formulas used are as follows:
Total bear form AC contribution = (Item AC+(Item AC*0.1))*5.5+2*(Item Agility *1.03)
Total dodge = ((Item Agi*1.03)/14.73) + (Item Dodge Rating/18.9) + (Item Def rating/2.4)*0.04
Miss chance = (Item Def rating/2.4)*0.04
Crit reduction = (Item Def rating/2.4)*0.04 + (Item Resilience rating / 39.4)
Final Crit Multiplier = (200-(Item Resilience rating / 39.4)*2)/100
Mob Crit = MAX(0,0.05-(Crit reduction/100))
Extra HP = ((Item Stamina*1.2*1.03)*10.5)*1.25
Armour damage reduction = (Bear form AC / (Bear form AC - 22167.5 + 467.5 * 73))

Total damage reduction = =1-((Mob Crit * Final Crit Multiplier + (1 - Mob Crit - 0.05 - Dodge%/100 - Miss%/100)) * (1-Armor damage reduction))

Scaling:
I noticed that the *relative* value of stamina for life extension declines as base HP increases. Initially this seemed a little counter-intuitive. It is however correct extra stamina ADDS a flat amount of hit points; all other factors effectively MULTIPLY your life total by the % of damage avoided.
Here are some values:
Conclusion extra AGI > STA on a 1:1 basis after around 19000HP on a strict "damage soaked" basis.
Using the above formula, here are some item comparisons:
Note the following gear is either "old world" items you may have left over, or easily obtainable "new world" items – from quests and 5-mans. Where sockets are available, the item is listed with no gems and with a combination of the following easily available gems to obtain the socket bonus.
Head, Back, Boots, Rings
Not many great new choices for helms here, guise of the devourer still seems the best available
Both Bogstrok & the Quest reward Valient defender are an upgrade over elementium threaded, which was amongst the best of the pre-TBC cloaks.
The easily obtained supple leather boots are a nice upgrade over the previous two epic favourites – I have not seen anything else that gets close for a bear yet
Violet signet is an upgrading reputation reward; the other two rings are both upgrades over previous offerings
Additional rings:
Heavy Dark Iron – 1552
Signet of the Fallen Defender – 1833
Both can be upgraded with pre-70 instance drops
Gloves, Legs, Neck
Once possible upgrade to replace the awesome gloves of the hidden temple, may be worth using even better gems than the "standard" ones
A green quest item provides a very nice upgrade to the tricky legs slot
Necklace of the Juggernaut provides some incentive to collect those heroic tokens to druid tanks and the next best option is a quest reward.
Shoulders, Belts, Wrist, Trinkets
AB reward still worth using if you have it, otherwise annoy your rogues by grabbing the assassination shoulders (gems & no gems line got shifted around)
Manimal's Cinch, a green quest reward provides nice belt slot upgrade to previous choices
The excellent Umberhowls collar fills a longstanding hole in bear gear, giving us a decent choice in bracers (Quest reward)
It's somewhat disappointing to see no prospect of a trinket upgrade – I'm guessing armour on a trinket was considered a mistake not to be repeated.
Finally – Chests
The hellfire quest reward beats out ghoul-skin and the other quest rewards by a small margin
