I do have the answers for some of the questions I listed. Unfortunately she doesn't have the mom's info on Berner Garde but she did tell me they were all passing and I didn't write down the male's name so that I have to get so I can look him up.
While she may be responsible for listing the dog on Berner Garde, OFA does is automatically if the dog is tested and has passed (other then CERF which she would submit the paper work on). This would be stop 1 for me, check and see that the sire and dam has ALL of the required testing for the breed. Berners at this time are CHIC required to have Hips, Elbows, VwD, CERF and Cardiac.
Do not take the breeders word that they passed check the fact for yourself!
All the dogs passing results will show on one page like this...http://www.offa.org/display.html?appnum=1360970#animal
Along with what you have listed I would also ask where the puppies are raised.
