Sorry, just to put my twopennorth in: your pup won't have any hipscores as they can't be scored until they're 12 months old. However you need to make both parents are tested with as low a score as possible, with the score from each him being balanced.
Usually the pup may have had it's first jab, though neither of mine had, though I think they innocculate them earlier now.
Researching your breeder and they're dogs is more important than colour imo, though if you can get the look you like from a breeder who has healthy animals, you're on to a winner

.
Good luck with your search. Oh, and don't forget to post pics of your baby when you get him/her.
