Well, I looked through your achievements to see what you would have the most access to. Seems you only run 10 man Raids right?
I was going to suggest the Royal Seal of King Llane, but you have not done any keepers or the rest of Ulduar . I can't really think of any trinkets off the top of my head but that is probably going to be the best trinkets you can get. You usually want to aim for stam, or even ones with Stam and a on use proc.
Stick with The Black Heart and Glyph. Fervor is good for some fights but not all. With the armor bonus from The Black Heart. You should get more benefit overall regardless of what encounters you may go through.
