This setup I linked above has the required resil and then goes full stamina afterwards. You used to be able to see resilence on that website... Now it just shows percentage however.. Its about as min maxy as you can get with frontline prot warr in wotlk.
If you are alliance swap pvp trinket with sindragosa's flawless fang and use your braincells to gem resilence to make up for the resil that you lost. Alternatively also swap your belt for wrathful belt if your struggling to reach cap as human.
