When i Started this season in nearly full PvE gear, i think with a pvp trincket (The removes debuff one is essential and going into arena without is silly stuff) and one offset piece (Waist, rings, neck those sorta things).
You just need a competent healer in that case.
Sub 1k rating, arena is a joke, just saying, so i couldnt imagine you coming across much difficulties.
As for gear, just get the PvP pieces, most of its actually better then what you get in raids pre heroic.
As for rotation, can't help much but id do what you normally do, but never stop moving if someones coming at you, and learn to kite with your traps properly.
