First off, you are way behind the curve on rep, get your Argent Rep, Ebon Blade, and Hodir rep. Boots and chest from Argent Crusade (but your boots are good so only if you really need hit), Enchants from the other 2, and also
shoulders, slightly better but not earth shattering.
Part of SV DPS is a lot of in combat procs, and being under hitcap you are robbing 3 points from Master Tactician (and another for Hunting Party), you just lost 8% crit in combat. Take 2 (or 3) from HP and put in Master Tactician, and I recommend getting hit capped through gear as quickly as you can.
Gloves and
boots need better enchants, and at this point I'd recommend changing a couple of gems, until you can get close to hit capped. If you can get 6-7% hit then Tactician is maxed, 10% crit is substantial in damage.
These leggings are easy to get and much better than yours, but have you been running Archavon to try to get some Valorous gear? And don't forget the Mirror of Truth to replace your PvP one. You have lots of PvP gear, try to replace it all quickly.
ExS>BA>SrpS>AimS>Steady is the rotation I use. But really, I've been over 3k for a long time and that was back when I had less AP than you have, getting your gear up so you can stack more agility will do big things for DPS.
