I have done a lot of coon hunting. I hunted with mostly Treeing Walkers, some Blueticks, some Black & Tans, some Redbones and some English.
Check out the United Kennel Club (UKC). They are the largest registrar of conn dogs.
For names of breeders who are more than happy to help you out, check out the Treeing Walker Breeders and Fanciers Association or the Bluetick Breeders of America. Just hunt them down on Google.
For magazines that give you lots of information and I believe have a web presence, check out Full Cry, American Cooner and I believe the UKC Magazine is called Bloodlines. The breeds you are interested in would have more of a presence in Full Cry magazine than the other two. The other two are focused more on the "traditional" coon hound breeds (Treeing Walker, Bluetick, Black & Tan, Redbone, English, Plott).
Hope this helps.
