I know its tough to get going as a prot pally and getting the gear up to cap your defense. One way to look at these things is to not worry about stamina right away and focus on the defense. You chest piece you currently have while the same one I use at the moment is hurting you defense wise when you dont have the shoulders neck bracers and trinket to build up a little more defense elsewhere. I would suggest getting the chest piece from the wyrmrest accord but I also see you are a bit low on rep for that. Also the defense enchant for helm from Argent Dawn but again your rep is too low. The chest piece from wyrmrest would certainly push you to 532 atleast and the enchant to it would get you the rest of the way. Of course this would be temporary until you were able to replace the defense elsewhere like in rings and trinkets that you are lacking all defense on. Otherwise I suggest just trying to grind out the emblems and getting T9 gear. You're on the right path to get capped but tanks sometimes need a few different pieces of gear to swap out to remain capped if another piece is an upgrade but lacks defense
