Damn, brewmaster monk gearing is crazy. agi flask, food, enchants, metagem, trinkets, the lot. Basically no tank gear at all. I tanked normal shek'zeer with about 230k less hp than the other (dk) tank, and took the same damage within about 1%, and did the most damage to boot.
It's akin to Druid Guardian and Feral tanking/DPS. There's no change in your gear aside from maybe how you reforge and gem.
Stagger is actually a pretty bad ass mastery, but you have to be careful with it to remove it at the appropriate times or else it can fuck you up lol
