I would use spotlights with fog attached to them for the main lights, as for the materials its going to be a case of lots of messing about to get it right, have a look in the help files for some advice on what each property of the matarial does.

Happymat27's got a greast 3 point lighing tutorial on his site, have a search for a post by him and his links there.

As for copyright, well if your going to usei t for something commercial then yes it would be sa prob, if its just for an private excercise then you'll be ok.
