Get your AUX ships to proper levels to deal with routing, and get the remaining worthwhile DDs to high level. After that, dupes for equipment and improvements are pretty much the only way to increase the power of your fleet.

As for luck modding, Abukuma is a good investment given her usual setups. A couple of CAs like Prinz and Myoukou are good to have as well. Then you can either focus on getting the top ships like Yuudachi to TCI standards, or focus on situational ships like Maya and Bismarck.
