Now that Armory is back up...
Here's a list of weak items:
Belt
Legs
Trinket
Libram
You want to replace those ASAP, grats on that banner tho, that can be hard to get ahold of at times. Seems like you missed Brewfest, sadly. You could have gotten one just like it.
Your Body and Helm are already purple, and actually fairly good ones to start out with, so I wouldn't jump straight to t8.5 right away; you could keep running heroics and doing the dailies as often as you can for more Triumph Emblems.
Hmm. I recommend getting a Libram first; you can be certain you're not going to get a libram anywhere but a vendor, get the conquest emblem one that helps you do more damage (you can just tell which librams are meant for which).
Once you do that, there's a necklace available for 19 Conquest emblems, that's pretty easy to get.
After that, you can save up emblems for a Valor-Emblem BoE wrist (you might also get lucky and see one on the AH, but they are usually expensive. I got lucky and found one for 1800g).
For Legs, run H-UK every day until Ingvar the Plunderer drops his legs. They are purple with 2 gems lots, very nice legs for a DPS. There's also an OK belt in there too (from Keleseth, the first boss), most likely better than the one you're using now.
