Gearing a Warlock from pvp gear to pve?

Hey i'm trying to gear my warlock for higher endgame content but i'm haveing problems. Alot of my gear is from pvp and i can not find items to replace them that are better without going into higher content. However raiders often insta kick anyone with pvp gear on. What i am looking for is someone to look at my gear on armory and tell me what pieces of gear i should get to replace what i have and where i can get them. My characters name is Wardlock and he is on Dark Iron. plz and ty
