No offense, but a little reading would go a long way to answer your current questions. After you have a handle on some of the basics, then it's a good time to start asking for expert help with the more intricate or complex topics.
To begin with, I suggest you go to the "Ovens" section, and read about different types of ovens, and what they are capable of. You may find that your preference in pizza style will steer you away from a WFO anyway.
Good luck!
