My suggestion regarding the requirements is to start taking classes to feel first if this is a path you want to pursue, and also to begin practicing the exercises you will learn more deeply in the training. As with any training, the more you can commit to understanding the work, the more you will get out of it. Two weekend workshops for Mat are really just an introduction to becoming a teacher. The learning process will be much richer if you engage beyond the structured class time.
