Are I-8, I-58, and I-19 remodeled into SSVs? If not, then you may want to consider remodeling for the second equip slot which allows you to have a torpedo cut-in setup. I-58 and I-8 have particularly good luck stats at Kai as well.

The job of sinking CA hime will very likely be left to your subs at night battle. Torpedo cut-ins are going to be your main source of damage to her, which is why it's best to have it set up on everyone you can. Your Boss Support and LBAS will mainly be for mopping up all the trash mobs that accompany CA hime to give your subs as few other targets as possible in night battle.

Modernising your subs would definitely help; especially if they are missing more than 10 torpedo stat. But it's possible to go without modernising and still succeed. However, it's also relatively cheap and easy to farm commons from 1-1 like you said, so if you're willing to put in the extra bit of time to do that then I definitely say do it.
