FSW is superior to the chest/shoulders. I am going to pick up the 2 piece T4 from head and gloves, while the FSW will be much better then anything else in the given slots until T5 (Robe of hateful, Corr better chest/Corr shoulders/boots last well into endgame(unless you need hit then go nightmare boots)). Another option if you need more spell hit is to pick up attunmen's gloves or the ones off mag. The badge offhand and trinket are really invaluble, the belt is good but yours is superior. Pick up the VR headpiece when it drops also the badge/shade wand would be a nice upgrade pve. CE exalted ring is amazing and would be an awsome upgrade.

Just a few gear suggestions :D I wouldnt waste a lot on craftables if your getting into SSC/TK regularly. The other thing is as the above poster mentioned using the Curse>UA>Corr>Immo>SiLi rotation will help. On trash if you are really concerned about dps use only spells that will run their full duration. If trash is going down very fast 3 shadowbolts over an immo/Corr rotation is going to be very much superior.

Affliction is a boss spec we will always fall behind in trash but in a 25 man like gruuls or mag we run the damage metre. Change up the rotation a bit and gear will come with time esp if you have a good guild.
