Oh, and about fleet: Ise and Hyuuga are probably going to be important, so you might put a couple levels on them more. Especially Ise is low compared to average of your fleet.

And maybe Tama. Frankly, I can't imagine situation where she's important for defeating boss or anything, but she might be useful for better routing. Levels are important for CL survivability, and while with combined fleet you can always make her flagship, with single fleet you are out of luck. Especially if you want to challenge hard difficulty.
