Top of list are 91 Ap shell (low cost 1 screw at a time, can be done any-day). 41cm. (best main cannon for BBs, however needs to eat 1 41 each time). 20.3 no 3 cannon (best medium calibre gun, however i dobut you have many of these so no 2 might be worth to upgrade too). Quint Tropedo (best tropedo in the game (apart from that 53cm which is unobtainable). use for CI setup)

I dont suggest upgrade radar. High cost not much gain.

10cm FD is very good but does eat quite a lot of screws.
