More info is needed to give any meaningful advice.
But your gear and stats distribution seems to be good.
Basic advice would be to maintain uptime as much as possible, have FF on as many targets as possible, positioning to maximize cleave, dnd on 5+ targets, when to use FwF and RW based on dmg phases, runes and RP available and what procs to prioritize depending on the situation.
Though i doubt you really need any of these.
Edit: This also assumes that you feast or at least mastery food + flask+stone and str pot on key PoF windows.
