As to your first question, coal was the most energy dense fuel available at the dawn of the dreadnought age. As soon as navies decided they had secure access to adequate oil supply, they changed over.

A 4 or 5 inch gun is unlikely to damage any component of a ship below water - the shells just cannot do it. Yes, they may be able to penetrate stern plating, but only at very close range, and the important steering stuff is not in the upper decks. Lastly, in a melee gun battle, there is little opportunity for “pinpoint targeting.” The focus is on getting as many shots on target as possible, not targeting specific sections of the target.
