levelling up and upgrade her to kai = remodel

sacrificing ship to boost stats to stats cap = modernization

remodelling usually gives higher stats cap and should be done. although there are a few cases (Chitose, Fuso-class) where remodelling have adverse effect which you need to reconsider whether it's neccessary.

about extra ship, keep the one you want to use (some quest need specific ship) and use the other as modernization material for your other ship.

put 2x12.7cm gun on the Destroyers and be done with it. DD are pretty much obsolete in  early-mid game and replaced by CL,CA, and BB.
