Keep all single-type weapon ships EXCEPT you want Point Defense Cannons. These will fire on incoming missiles, fighters, etc. They also get a 70% to-hit bonus and abosultely butcher what they can hit.

DF weapons are actually better than missiles once you get them high enough. Missiles simply don't fire enough. Remember on your Cruisers and Light Cruisers to click the Weap Mount button and use Large Mounts for your direct fire weapons. that increases they're effectiveness quite a bit.
