Akizuki class guns (best DD gun), 20.3 (2/3) for CLs and CAs, 35.6/41cm protos for BBs, Seaplane fighters for CAVs and AVs, Zero fighters model 21 that can be upgraded to skilled 21 or 52 through the monthly quest once maxed out. AP Shells are really important as well. Personally I think it's worth maxing out the night scout once you have a few screws saved up, it's expensive but worth it in the long run.

It really depends on what are yours priorities. Look at what ships you use more and what kind of equipment you're lacking so far, then start upgrading the stuff you'd end up using more.
