I edited the Item.xml file from Rawr 11b to include the new armour values, if people don't know how/can't be bothered to do it themselves:

Edit:
Okay had a bit of time to do some theory crafting. It isn't possible to hit the armour cap without Badge of Tenacity still. However we can get close:
[Mask of the Fury Hunter] (10 agi, RED)
[Pendant of Titans]
[Thunderheart Pauldrons] (5agi/5hit, 5agi/7stam)
[Slikk's Cloak of Placation]
[Harness of Carnal Instinct] (10 agi, 5agi/5hit, 5agi/7stam)
[Thunderheart Wristguards] (10 agi)
[Wildfury Greatstaff]
[Idol of Terror]
[Gloves of the Forest Drifter] (10 agi, 5agi/7stam)
[Thunderheart Waistguard] (10 agi)
[Leggings of the Immortal Beast] (10 agi, 10 agi, 5agi/7stam)
[Thunderheart Treads] (10 agi)
[Violet Signet of the Great Protector]
[Ring of the Stalwart Protector]
[Shadowmoon Insignia]
[Commendation of Kael'thas]
So selfbuffed (non imp-Motw only):
HP: 18264
Armour: 35090 (74.58%)
Dodge: 54%
Raid buffed: (imp pwf, imp motw, comm shout, GoA, BoK, Elixirs of agility/fort, 30 stam food):
HP: 23556
Armour: 35592 (288 armour short)
Dodge: 67.6%
With Idol of Terror proc on (most of the time) you are only 140 short of the armour cap and have 72.6% dodge and you can get another 40-50 armour using 20agi food instead of 30 stam food (as well as going up to 74.26% dodge).
If you were really a stickler for being armour capped you could always swap in
[Gilded Thorium Cloak] for the extra armour it has and then you'd be 28 below the cap.
