No crocodiles do not have a shell, but contail hard scaly skin that protects them from injury. Images of crocodiles and more information on the subject can be found here: http://en.wikipedia.org/wiki/Crocodile
They shed their skins because snakes keep growing in length until they die and the skin does not stretch, so they shed it every once in a while, the new layer of skin underneath is longer. Experts can tell the approximate age of particular snakes by studying the length of the shed skin.
crocodiles skin has a smooth layer on the bottom side of their body (stomach) then on the top side (back) there is a layer of rough and bumpy skin also quite leathery.
Nope - lizards do it too. Humans shed their skin (but not all at the same time like reptiles).
If I remember right, alligators have scales called 'scoots'. I think the fall off and regrow once in a while. Google scoots on alligators or something :)
crocodile skin is like armor and most snake fangs cant stab through a crocodiles highly armored skin.

Shed
Geckos shed old skin because it get old and dry and so they can grow bigger, we shed our skin to it takes a whole year to shed the whole of it but we do shed too :)
As snakes grow the skin doesn't grow with them, so they shed the skin because it no longer "fits" them. By shedding the skin they can get larger, and grow.
