DK after 80.. need tips

Hello guys,

I'm writing to you to get some tips how to develop my DK after hitting 80 and gear. I'm the type of guy who loves path of 1-80lv in wow and always after hitting 80 I was making new class character. Now due to that I'm still newbie about after 80 game. My DK is 5665 GS, with most of items PVE. I found some good stuff at Orgrimmars Hall of Legends and bought it, but now idk where to find other worthy items to spend currencies. At this time I have:
-75k honor points
-247 stone keepers shards
-63 EoT
-28 EoF
-20 wintergrasp marks

What would you suggest to spend it on and focus what to do right now?

Appreciate every tip.

What is your goal?

Can't really recommend what gear to get, when we don't know what you want to do, or focus on, and what you have already.
