Help! Breastfeeding/ formula paraphernalia FTM

I am 29 weeks with my first, I’m confident we are stocked up with most everything we need EXCEPT bottles/formula/ pumps etc. I’ve never had a baby before, I don’t know what to expect, I don’t even know if I will be able to breastfeed and will need formula or maybe I’ll just need some to supplement or maybe none at all. I’m very overwhelmed. My questions are:

- should I expect to be able to breastfeed and purchase a pump before baby arrives?

- should I expect to at least supplement with formula and buy formula before baby arrives?

- at the very least should I buy a hand held pump for relief if the boobs need to leak?

- are bottles for breast milk and bottles for formula the same?

- what is pumped milk stored in? Is this compatible with any nipple top?

Thank you in advance ladies! I’m getting so anxious over this!
