The minimum looks like a guideline for medium and hard mode. If you can pick up your resources around every 2 hours, you should be fine heading into the event at 10k resources, assuming you're on easy.

Buckets are always nice to have, but not strictly necessary in such grand amounts (ie. 300+) if you have the patience to wait out your repairs. If your ships are in the high tiers though (around 75+), then buckets become a lot more important as waiting the timers out is hardly an option. I was using around 5 hours as the limit for whether I would bucket or not last event, which resulted in around 3 attempts per day, assuming I had any major damages. E-5 only ate around 30 buckets in total.

If you plan to go on easy, equipment is a lot more important than resources. The RNG is a lot kinder (unless you're cursed) and preparations that sway that are a lot more effective. You can probably get away with only using Type 21s for some of the map, though it will likely have the effect of turning your CVs into AS-only ships (AKA they become sponges after the aerial phase).
