Keep in mind that while all those morphs are in existance per se the only readily available morphs are blonde and silver(axanthic blonde) and to a lesser degree ablino's.
There is only, as far as I know, a few albino blondes and only a single snow(axanthic albino) in existance currently.
You can get much more detailed info on them from Dusty's sight which is linked in his signature in his post above.
PS: as far as handling they are great, just remember to not react if they tag you and to not put them down until they calm down in your hand. After a single session(about 10 min) each doing this my trans peco's settled right down. Now as long as I only handle them passively and calmly they are completely comfortable lounging on my hands for as long as I let them. Although you do want to be careful not to stress them out so depending on the snake might want to minimize handling as babies.
