Morph Research for NARBC

I am hoping to pick up a female if I see one I like at the NARBC conference in Arlington next month, perhaps a pied or a clown. I do not plan to start breeding immediately, but down the road I really want to, so I figured... hey she'll need lots of time to grow up, anyway! I've found a lot of sites with very basic abbreviations of different morphs, but not so many with information that covers both the basics and a more extensive overview of the morphs. I want to thoroughly research some morphs before I hit the conference in August. Last reptile show I hit, I had no clue how to tell good examples of morph from poor examples and, let's face it, whatever morph it is, those smiley little ball python heads are cute, cute, cute! (Or is that just me? I also make kissy noises at snakes. Hey, everybody needs a hobby, and anthropomorphizing animals and occasionally favorite pieces of furniture is mine. ;P)

Are there any sites that, along with basic info, list the things that are genetically desirable in morphs (ex: "it should have a reduced pattern and better examples of the morph have no spots") , what to look for if you want to breed, etc? Or should I just keep browsing the forums? I see people asking about what snakes are better quality here, and at this point I just can't tell! I'm sure it's a long process that involves looking at a lot of snakes, but a base of knowledge to start from would be nice.
