Everyone's been doing heroics and while you are doing heroics you best be wearing a tabard! If not... then I don't really know what to say expect /emo
Now the badge gear is really nice but rep rewards are going to fill your gaps to help get you ready for raiding. First stop on the rep reward train is Wyrmrest. Our buddies there have some really nice items that fill in gaps quite well. Revered with the dragons gives you a nice selection of items, and the reason I mention the Wyrms first is because well...They have the inscription for your head I think we'll all be looking at. You can also nab yourself a decent Mace. The only thing it's missing is MP5. It does however have good stats, crit and haste. This is good as well if you decide to switch it up and go off-spec elemental. Now at exalted, not only do you get a cool Drake to run around on but you can snag Grips of Fierce Pronouncements which are well worth the 28 gold if you ask me, I mean just look at those stats.
Next stop is Ebon Blade. That sexy Duchess has a really nice goodie for us in the form of this awesome Kilt.
Good stats and two sockets to boot. She doesn't really have anything else that benefits us too much so I wont dwell
On to the mages of the Kirin Tor! Their Quartermaster actually has a number of things you might be interested in. If you want a little crit and don't mind leather This belt will be right up your alley. The Robes at exalted aren't bad. Good stat allocation and 26 mp5. Worth picking up till you can get something better. The head enchant is also good if you are trying to stack crit raiting. The leather helm from there isn't bad either, decent spell power and mp5 and it looks kindda cool. The last piece from here is a Haste Cloak It's not bad but you can have better crafted. It's a definite filler piece and will serve you at least into 10 mans.
Argent Crusade only really has one thing you might be interested in so I'll just point it out real fast. This helm isn't bad if you are stacking crit
That's pretty much it for the rep rewards worth snagging to fill in gear gaps, chances are if you're running heroics you won't have much to worry about but figured I would put them out there for you guys to take a look at.
Hope it helps
