first time mom I need advice please!

When it comes to the small things a baby needs I don't really know how much of each thing to get. 
Things like : 
Burp cloths
Pacifiers 
Baby wash cloths
Baby towels
Bibs
Bottles
How many of each is really needed? 
Also what age can they use a pack and play? And what age for a high chair? 
How many sets of sheets for a crib? 
Do pack and plays need sheets? So many questions I'm sorry. 😭
