I'm not a PVPer but here are your answers
Your gear depends on match up
You don't have enough skill points for ES
I'm not sure if pure vita is better than vita max block......Depends on your match up you should probably do both and have tokens.....
FHR doesn't do shit anymore so no need.
I would assume you want max damage or near max damage. Fathom, nightwing, enigma, spirit, arach, trang, 2/20 amulet(whatever you need for %105 with spirit), BK's or SOJ's, charms...
Again I'm not a master PVPer but their is only so much gear in this game so it should be easy to get close to perfect.
