Overall I'd say upgrading the AA fire directors to the 10cm+AAFD and 12.7cm+AAFD is the most important use of your screws, getting those AA cut-ins simply makes such a difference. It's also worth remembering that the 10cm+AAFD is overall the best gun for destroyers and I sometimes use it to get cannon cut-ins during night battle on Ooyodo.

Upgrading torpedoes isn't really worth it, not because the quint torpedoes aren't good, but simply because screws are hard to get and the torpedo cruisers give you quints at level 50 which is pretty easy to get if you are grinding on 3-2.

Beyond that, simply getting stuff that can't be acquired on ships should be your next priority. If you don't have Katori it's nice to get a 14cm twin gun to get it in the library (probably not worth getting any more than one though). Getting some 35.6cm triple mounts is generally quite useful, particularly if you like using the Kongou-class, and is relatively screw efficient. It also can be worth it to get some extra 38cm Kai mounts from Bismarck, unless you have plenty of medals and blueprints in which case it would probably be easier to simply build, level and remodel another Bismarck instead (which also gives you lots of other goodies like 3.7cm flak).

Once you have all the gear you want, focus on improving the gear that you find yourself using most of the time. For example the 10cm+AAFD is used whenever I use destroyers (and sometimes on light cruisers too) so I can get a lot of use out of the extra damage upgrading gives.

Lastly, never do any equipment improving except as part of the daily quest as it overall improves your screw efficiency so much.
