Some breeders give them shots and some wait until they go to their new homes - Primetime has the right schedule.
As far as your concern about getting the puppy shots and transitioning to your house, puppies are pretty resilient and having shots is not a horribly traumatic event, but after shots if you give your puppy lots of attention that can be a good bonding experience for you two.
If you are worried that the vet may find something wrong with the puppy after you buy it, you can ask the owner if she will give you a health guarantee. My mom was a breeder and gave a health guarentee with her puppies.
