PeroimFeld's advice is pretty solid, but I would quibble slightly with the equipment list.

I think you should decide if you prefer the prototype 35.6cm or the 38cm twin kai and then upgrade several of them. I have four upgraded protos and my two upgraded 38cm kais are probably rusted out at this point. My two upgraded proto 41s just sit in my base (read: useless) unless I break out a Fusou or a Nagato, but that's just me.

Quint torps, because of how useful they are for events and how they can only be upgraded two days a week, should absolutely be placed at the top of your priority list. 10cmHA+AAFDs are also a solid investment.

However, I would advise heavily against upgrading 20.3cm (No.2)s. Those do not give your CAs the 15% night battle accuracy that the (No.3)s do. I would upgrade the (No.3)s that you can and either farm Kinugasa or passively collect Mikumas from basic LSC tries (Maruyu farming). That being said, it's much easier to get (No.2)s to +9, so that's ultimately your call. Five or six (No.3)s +4 should be enough for almost everything outside of 2-5.

No one would argue with AP shells, though. Or fighters, for that matter. I would put elevated importance on fighters, since you'll use them every time you sortie a carrier, and remember that once a month you can convert a Zero Model 21 (Skilled) +10 into a Zero Model 52 (Skilled) +10, giving you a cheap 11AA fighter with accuracy and evasion.

For radars, though, I only use the T13Kai and the T22K4. Since BBs get AP shells, large radars are only good for CAs. Now, this point is up to you to decide, but I only use T32 radars on exp grinding fleets, and in actual sorties, I only use one, maybe two, FuMO radars. Now, I know you don't have any of those, but if you do get them, they will make your T32 radars obsolete (in my opinion) which will relegate them to exp grinding duty. In the mean time, however, you can use your T22K4 radars on your CAs, as they both grant +8 accuracy, and I can't really think of an instance where you would be allowed to use CAs that you wouldn't want DDs to have either a torpedo CI setup or an AACI setup. Again, up to you, but I would recommend upgrading other things first and thinking about which radars to upgrade.

For ASW, the T3 depth charges are an obvious upgrade, but you can decide on which sonars to upgrade. The T3 sonars are easy, but if we're worried about obsolescence, you might be better off upgrading T93 sonars into T4s. I've got seven T4s, personally. It's not that expensive, but it does take time. I would especially think about it because you're not already sitting on a fleet of upgraded T3s.

For a quick list of relative importance, I would say Quints > Fighters > Guns > ASW > Other. Anyway, that's just my two cents. Hope it helps.
