Warlock Gearing - Need Help

Hello all,

Quick question for gearing my warlock, I just got the 408 ilvl helm from vault today with haste and versa (not a set piece).

I did farm 1900 conq and I am trying to figure out what the best upgrades would be for my guy. Is Staff better than the 1h and Off-Hand?

Should I get other pieces first and then worry about the staff?

I am a solo player through and through, I mainly do PvP since it’s not as time restrictive and then farming content as I level up my enchanting.

Link to my Warlocks profile. Any help is greatly appreciated.
