Something like showing and acquiring a show dog is something you don't want to rush. So far it sounds like you're doing your homework. Good Job!
If you found a reputable breeder in your area already I would stick with him/her until she has something for you. IMO sometimes it's better to start off with showing a boy.
Anyway I would like to Welcome you to YT. Maybe other members may have more advice for you.
www.ytca.org is a nice site to visit and they also have a list of breeders.
