You either have a bad stator or regulator/rectafier
yes.
A storm has nothing to do with the battery going dead.
If the battery is over 3 years old, suspect it has a dead cell. It can also be that something is drawing current. Possibly a glove box light on, trunk, under hood, etc.

Bad battery cable connection or dead battery
Yes. Just make sure to use a battery of the same voltage.
The battery keeps going dead.
You do not have to reset the fuel pump just because the battery went dead.

Charge it, test it, replace it.
Can anyone tell me why my new battery goes dead in my 1997 Buick Ultra Park Ave?
Depends on the output of the charger which you did not list. A dead battery can be recharged with a 10 amp charger in 3 hours.
