Focus on getting 2-3 of every ship type in the game (preferrably more for some types like bb or cv), and leveling them to a decent level. In general, starting to save resources around when it's announced, or a little before should be fine, especially if your ships are ready, since you'llsave a lot of resources (and sanity) by not having your ships rekt or shiplocked.
As for buckets, you can just keep doing exp. 2 for them, and you'll have a decent amount by the event. Also having a lot of resources wont help if your ships are underleveled, so def. Focus on that.
