It doesn't look like you've progressed very far as far as raiding is concerned, but I would definitely take the time to get epic cuts for your Mooncloth Vestments at least. You'll be using them for a rather long time, and putting good gems in them will get you a long way. (I'm pretty far into tier 6 content while still wearing frozen shadoweave, although I suppose it's not QUITE the same thing.)
Since you can now buy epic gems from the badge vendor, you can look to purchase them that way. One full Kara run will buy you one gem, and the better part of a second one. Doing a few five-mans inbetween raid type activities will get that finished pretty quick.
Of course, if there's other gear you need from badges, get those first! And it looks like you have quite a few things you need to get still, so I would do those as soon as possible.
