What do I need to know about technology integration before I become a teacher?

I think that the main thing that I need to learn about technology before I become a teacher is what my options are. As of now I have very few ideas on how to incorporate technology into an art class to optimize the student's experiences. Once I learn what some of my options are I need to learn how to incorporate my lesson plan goals with that available technology. I also need to learn about what type of methods dealing with technology have been proved successful so that students actually learn from the experience. There are a lot things that I do not know how to do, some of these things include making spread sheets, setting up a class room, creating lesson plans, or using a smart board.
