First time mom help

To start off I am a first time mom and don’t know much about breastfeeding. I’m breastfeeding my 3 week old about 8-10 times a day and pumping right after she eats. I’m pumping about 60-72ounces a day. Is this good? Or enough? I have big boobs so I think that helps. I go back to work in 3 weeks and really want to get a good stash going.
