Woops, forgot I still had the lvl60 weapon in there. Oh well.
Yo!'s Enhance Shammy Sim; since we're talking Kara I'll assume one Blessing (Salv), Sunder, Battle Shout, FF, LotP, and MotW for buffs. I also assumed twin S1 axes with Mongoose, so that doesn't have a huge impact, and did Abacus/Hourglass without the Abacus proc (since the calc doesn't support it and I don't feel like mathing it out).
Ten 100-hour sims (since my computer doesn't like the longer ones):
Yours - ~954dps
Mine - ~987dps
Higher damage by grinding out non-PvP stuff (well, at least for a lot of it), not to mention that - depending on battlegroup and such - the non-PvP stuff probably won't take as long. Badges gear pulls even farther ahead, on items such as the leather bracers and boots, the cloak, and the mail gloves. S1 gear, save the weapons, isn't worth it for PvE when there's better stuff available from *non-heroic 5-mans.*
Of course, this is all assuming the OP is even interested in PvE (I just thought I'd point out to be careful with PvP stuff in PvE because I've seen too many people grind it out thinking epix = good raiding gear). If he's purely in it for PvP, then get the weapons followed by the shoulders, and then upgrade further from there.
