Hey Bob,
You're in the right place, most of the time. I'll try to answer your questions in the order you asked them below.
>>Am I in the wrong forum?
No. Sometimes we get carried away with dumb stuff, but this is in fact probably the best source of leopard gecko info on the whole Internet.
>>I would suppose that many here are ardent breeders of Leos,
I've bred a few in my time and currently have something in the neighborhood of 50-ish. There are people just starting out with one gecko and others here who probably have 100 or more, possibly.
>>but I have seen so many statements concerning them that I have to ask, Is there a manual that identifies all these types and morphs of Geckos?.
The best single-source document you can buy is the Leopard Gecko Manual by de Vosjoli, et al. But, never settle for just one source, so check out some of the online sites, such as-
Dream Gecko Leo Morphs
Geckos Supreme - The melanistic is an African Fattail gekco, I'm pretty sure.
Article in Reptile Rooms
There used to be some great resources for this question, but they're gone now. If you have some specific questions after seeing those, just ask.
>>Also, I often see thngs like "Leopard Gecko 2.8, or 2.1, or whatever. Nice, I am happy for you, What do you have?
The numbers you see are male.female.unsexed. The unsexed hatchlings are sometimes omitted from the 'tally'. So, 2.8 would be 2 males and 8 females.
>>Same goes for calling some of them "Hypo Tangerine, (Orange in color?) and I am guessing that the statement of Carrot on the tail is both a good thing and a description of an orange touch of color on the tail.
Yes. Hypo is short for Hypomelanistic, or less melanin, which would mean less black spots on the gecko(mostly lacking on the back). I'm a firm believer that a 'Hypo' gecko needs to have 10 or less spots on its back. Super Hypo would have zero spots on its back, as in this picture.

Welcome to the forum. Stick around a while; most people here are really cool and willing and able to help. Searching the archives will usually give you answers quick, though. The forum has been online since around 1999/2000, so there are literally years of answers in KS's servers.
