If another Tac player sees you mixing energy weapon types, they will chastise you to hell.
None of my chars use Engine or Shield Batts. Engrs and Tac use Weapon Batts, Sci uses Aux Batts. If you have any of these devices, I recommend using: Red Matter Capacitor (from Collector's Ed), Enhanced Plasma Manifold (from Oberth), Subspace Field Modulator (Devidian FE).
I would not put a torp on the rear unless you were planning to do flyovers. In that case, it would probably be a tricobalt mine.
My Tac officers use turrets for aft weapons. Phasers or AP with [Acc].
I'd replace the Bio module with something else.
I don't see any cannons on your ship, so ditch the Prefire Chamber. Get a Directed Energy Distributed Manifold or if you go with a single energy type get the appropiate console.
