Storyboarder by WonderUnit was one of the best discoveries for me!
Allows you to build virtual sets, using 3D objects and then take pictures with a virtual camera (that can change focal length and everything).
It links in with your script, meaning you literally build shots off the lines and directions.
Such amazing software... And it's free!!
I highly recommend this book to get started. There’s an audio book too. It’s really informative and I’ll help you through your first experiences.

Taking a few acting classes will help too, as well as participating in a few directing workshops.
