Firstly, thank you for the compliement and kudos for doing your research FIRST as so many do not, it seems.
It is never too early to start having them evaluated. Try to find someone in your area who is expericed w/ the breed to guide you. At an early age, you can't tell for certain if the dog will be breed quality, but having someone help you and point out what to watch for and how the dog matures and changes as it grows is going to be a big benefit to you in the long run!
Ideally, you want a dog with rich gold and a steel blue coat. Sometimes breeders will introduce the darker colored black and tan to bring back some of the rich color if it starts to get 'washed' looking.
Regardless to if they end up being breed quality (which should be determined at 18mo-2yrs), assume at this point that they are where caring for them...diet, excercise, etc are concerned. Especially if you think that you would like to show them. Don't wait until you find out they are of excellent quality to start this!
Try to get as much history on the lines as you can. You definately seem to be heading in the right direction as far as having them screened health wise!
At this point, a well seasoned breeder and an excellent vet are going to be your best friends on your quest.
