Your gear is fine. I would suggest upgrading your helmet and shoulders, but I know that Bold shoulder drops suck (not from experience, mine dropped first time =D), and your helmet is alright as well. Overall, your stats look about the same as mine with my Fury spec, which is good for the first few bosses of Karazhan, up to Opera and maybe even Curator depending on how geared the rest of your group is. The only other thing I can think of is [item]Adamantine Figurine[/item] from Blackheart in Shadow Labyrinth to replace that Fungalcap, or [item]Dabiri's Enigma[/item] from a short quest chain in Netherstorm for the use effects. You could also replace one of them with some kind of stamina trinket, because you don't necessarily need or want any more defence.
Edit: Good luck and welcome to Tankspot!
