Not really, i don't understand why people get so hung up on gear, it's a means to an end, i couldn't care less if someone who can barely complete 2 quests was decked out in 277/284 gear whislt i'm still in a mix of 277/264, it doesn't bother me.
Epic is just a colour and always was, sure it might not have been "easy" (Depending on your point of view) to get decked out in full epics, but it was hardly dependant on individual skill for the most part.
Not only that, the previous two expansions have allowed you to get top level gear in the weeks/month preceding the next expansion simply because it allows people to get a feel for changes in other classes they may wish to try out and to give an opportunity for people to be at a similar level when it comes to levelling ability.

Gloves / shoulders are around 650 justice points each with legs/head/chest being 1100 justice points each.
I'd advise reforigng your gear if you have not done so already as you'll be massively overcapped for hit without it due to the talent change
Elitistjerks has a pretty good shadow priest faq which should have what you need in regards to what to reforge to.
Incase you're wondering the reforging npc can be found in any major city parked near the enchanting trainer
