Just a quick bit of advice, do a scroll down on this forum. This exact question has been asked more times than i can count. Not being mean, just short on time right now.\

http://wow.allakhazam.com/db/class.html?wclass=5;mid=118203468330282849;num=199;page=1 Contains all the data you could want on gearing yourself. Everything from what item for each spec, to where it drops. I will say that you are on the right track. Your Agi is very good. Keep doing Kara if you can, do as many heroics as you are able to for badges and the gear will come. I have not played as SV for a long time so will let the SV kings here add their 2cents.
