Then get your HP to over 10k (Solid stars everywhere, 30/40 stam leg enchant etc (actually I still use these))
Then depending on team makeup, push your resi to ~400 (S3+honor gear does this for free)
Then re-gem for AP/Crit/Agi depending on spec to keep your resi ~400 and HP over 10k.

Get the best weapons you can - I'd save up all your arena points for the S2 weapons if you can? Weapons make a big difference for a Rogue...

I'm at 10.9k HP and 409 resi with dps gems in every slot, pretty much. I'd probably wear more DPS gear, but my DPS stuff is T4 with a few pieces of T5, so it's a big ilevel step down from full S3, even if it is more offensively statted...
