One of my favorite online fashion pundits was recently asked how to start out with makeup. I liked her advice. She suggested taking one thing you like, such as mascara, for instance, and learning to use it until you're comfortable with it. Then experiment and add other things as you desire, but gradually. The most important thing is to know it's far better to underdo makeup than to overdo it.
For we M2F folks, I think the most important thing to start with is looking for a good way to cover the beard shadow. To my tastes, anyway, if you got a beard, obvious makeup looks don't really work. There are a number of products and methods and many are discussed around this forum.
