Things to know when putting on a show?

My band (high school rock band) is ready to put on our first show, and I just want to everything from how to advertise, to how to plan the actual concert, choosing a playlist, and entertaining the crowd. We play mostly clic rock (U2, Beatles, Who) and also some blues. Also, how do we find a place to get gigs? Just please tell me anything i need to know about the whole entire process of putting on a concert
