New to the game

These questions have probably been asked a million times before but I would like to make my own post to get some insight.

I'm not a ftm but I used disposables with my first due to not having a washer.

So far, I got 6 pockets (I think that's what you call them. Or panties), 20 prefolds and 6 pads/boosters. I also got some disposable liners cause I want to try out both and see what works best for us. The panties come in 2 sizes with this brand. Up to 9kg and starting at 9kg. I only got the smaller size for now.

Is this going to be enough or do I need to stock up?

Am I missing something? Aside from the detergent and bucket. I have both at home already.

I'll be using the disposable diapers at the hospital until we get home cause I don't know how long we will be staying there.

I would like to wash them every 2-3 days. Not every day. Can I wash the pockets with the prefolds? Or do they normally need to be separated?
