I know it's frustrating, but you have to be persistant. It is disheartening to get the 'you have to show to breed' or 'how do you know if you don't show' spill, but when you try to learn about it, everyone turns their back on you.
I know there are alot of show breeders here who view the world of showing with utmost importance. Hopefully one of them will step forward and give you some help or at least some hints.
Just hang in there...good luck!
