Cloth Diapers 101

My husband and I just found out yesterday we are having a baby boy! We started talking about diapers and everything else. I used disposable with my daughter and we are thinking this time we want to try cloth. After many google searches and still being clueless and overwhelmed I need some help.

What brand do you use? What all do I need to buy? Do you ever have problems with them leaking? What do you wish you had known from the beginning?

Thank you in advance for the help!
