I agree that you want to go with all turrets aft and you're really gonna want to lose the quad cannon. They aren't very good regardless of how cool they may look. Ditching the beams and torps in favor of turrets will allow you to stack more consoles for the flavor of weapons you've chosen.. For example; I run 4 MKXI anti-proton mag regulators in my tactical section.
Your specs look pretty good as far as I can tell with the exception of "Ship Threat Control". You don't need to be spending points on that for an escort ship.
Also; be sure your Ship Power Level is set to "attack" and not "balanced" or "run away".
