This was my attempt to design something like the Modular Cutter from GURPS Traveller. Many of the questions you asked would depend on how, exactly, the ship is designed, but normally a module would be designed to fit a specific ship or a specific universe (such as Traveller) might have a standardized module size that all modules would conform to. How the performance, the Modular Cutter itself doesn't get any real performance benefits from not having the module installed because the module serves as part of the structural reinforcement; without a module in place it can't accelerate any faster as it would risk breaking it's back in such a maneuver.

Performance may increase, but it may not as there may be inherant limits to the systems or the ship's design. I wouldn't change dDR; the shape of the ship isn't changing, neither is the thickness of the armor. There's no reason dDR would change.
