Similarly to badger I am a little confused to what you mean in the second question, if your asking how to set the camera size then check the render globals, if your trying to render it out check the newbie forum on this very site and if your asking how you want to actually rig, animate and render a scene in maya then check both the forums and the help files. For instance animating the scene involves modelling the character, rigging them, animating them, lighting the scene and then rendering it out.

But good luck to all involved and I'm sure it will come out awesome.
