Hi,
Best thing is to contact her breeder, who, if reputable, will be able to tell you if she is of the right quality to breed from. The breeder will also know which 'lines' will match well with her, and which lines to avoid. Go to a few shows and see which dogs you like the look of, and talk to their owners. And of course make sure she has had all the breed-relevant health tests; hip-scoring, eye certification, hearing test etc!
