Breast pump/ feeding questions!

So I get a free breast pump, my insurance is paying for it and I’m picking it up at the hospital medical supply store after I deliver (can’t pick it up before 😞) . What all will the pump come with? I got the Medela. I’m a first time mom and don’t know much about breast feeding but I know 100% I want to breastfeed. Will the pump come with storage bags for milk? What do I need to buy to help support my breastfeeding journey? I bought some lanolin cream but now I’m reading that’s not good for baby. Can I just use aquafor for dry nipples? Will my nipples hurt that bad? Any advice or tips? Really want to be successful in this!
