Nursing supplies

Hello moms! 
I am planning on breastfeeding when my little girl arrives in March, but wanted to ask what products do I really actually need. 
Right now I only have two nursing breast pads (don't even know what that's for?), a few nursing bras, a nursing cover, annnddd.... A boppy. Oh and a pump with two bottles (that came with the pump). What else would I need? Nipple cream? More breast pads? More bras? More bottles?!?! 😱
