When people ask how they get started breeding or if they have question about breeding, my first response is always, "Do you have a mentor?"
I always suggest finding one to work with FIRST before even worrying about any other details. Having a well experienced breeder to help guide you and help you research and learn is really the best place to start. He/she can best help you prepare and learn about all of the other issues you addressed BEFORE you actively start trying to breed your girl. In addition, a mentor will be key in helping you to evaluate your girl to determine if she is a quality representation of the breed that should be bred.
Contacting the breeder you got your girl from would be the obvious, best place to start looking for one, I would think.
Good luck and welcome to YT!
