Breast feeding help

So I’m wanting to breast feed and I’m hoping to get most of my answers here rather than having to go to a class. What are some tips for breast feeding? How long do you feed your baby on your breast before burping them? How often did you find pumping worked for you? How long can breast milk stay at room temperature? How long can breast milk stay in the refrigerator? How long can it be frozen for? Once the milk is frozen what is the best way to unthaw the breast milk? What is the best way to heat the milk up? These are just some questions I had if you can think of anymore helpful advice please share. Thanks in advance!
