I have to agree with dahminus on your build. For a successful build you want to maximize your firing arc first. In your case go either full beam arrays, or full dual heavy cannons with turrets in the back with a torp thrown in somewhere. Because this is PVE you don't really need the spike damage, but I usually like to run a dual beam bank up front with a beam overload three backing it up. Really isn't much I can say that hasn't been stated above.
You would be better off with a escort/fleet Mogai with more hull and battle cloak. Your build fails to leverage the abilities of the enhanced battle cloak. The T'varo should be a torp and mine boat, and you should not be getting into prolonged dogfights with this ship. Go all transphasic torps front, adapted MACO or KHG, a mine of choice on back with a Breen Cluster Torp, Dispersal Pattern Beta, crit consoles, assimilated console, Rule 62 console, stay cloaked, and blow up your enemies with their shields at full and their hull at 0.
