Have you tried looking up http://akashi-list.me/? If you haven't there you can see what kind and how many bonus from each level of improvement for  every equipments, along with upgrading material, secretary ships, etc. Sure its in japanese but i think just by seeing the layout its quite easy to understand and get the information you need. Just check with wikia which word stand for what stat of the equipment.

As i too am still figuring things out with my own equipment improvement i can't say much, but i remember someone once said in these threads that you should improve guns (or any equipment) that you usually bring in sorties first. Also prioritize those that gives fit bonus the most to your ships.

Personally i think your fleet seems well enough to challenge Normal but just keep going with your levelling plan. Back then when i was trying my early Normal/Hard maps with my it-seems-underleveled-fleet i always give the map in said difficulty a run once. If i can make it to the boss then the map is doable (keeping in mind the number of chuuha ships should be acceptable). After that if i can make the boss to at least taiha then i can clear the map (or A rank if its TP map).
