I'm starting to freak out...?

You don't need any pacifiers or bottles. It's best to not introduce a pacifier in the beginning (or at all) if you are feeding. The hospital will give you one too if you want to take it home for later. You have plenty of diapers, no worries. Bottles shouldn't be introduced until at least 4-6 weeks, if you eventually need to pump for work. Just a side note that the bottles that come with the medela pump are horrible - they leak terribly. We used Born Free when I went back to work - no leaks, easy to clean. If bottles are only going to be used because you are away from baby then you really only need a couple.
