Well first, what kind of latency are you working with? I'd say that is the largest factor as carnage, lag is killer for the spec. Otherwise make sure you get a mix of weaponmaster and the other one, forgot its name, but it shares the bonus with weaponmaster. You are shooting for power+surge, (optional: with a little crit thrown). Full weaponmaster has some pieces without power surge so you would want to use the power/surge pieces from the other set. For pvp, rotations are more of a guideline rather than a rule, as you have to adapt, but you got the general idea. I don't use rupture as carnage though, I suppose it might be useful in certain situations, but I rarely use it. Also, don't forget the dual saber throw, that one is helpful, and free. Use those stuns too, a well placed aoe mez can keep you alive a lot longer. Also, if you are pugging, your numbers can sometimes be low. I pug primarily and I'm around 850-1k dps on average, but in a group, with a somewhat dedicated healer, and guard? I could probably go for 1.6k or so, depending on the heals for the other team.
