Enjoy your C&D ! and i hope that script is a legal version too - the script makers won't be happy either.
wow, please think of a unique name. If facebook finds this, they will probably have better lawyers than you and take you for as much as they can, sell it on while you still can, don't promote it.
You can't set up a website with the same name - like was said before, its copyright infringement. At best you'll get away with a cheeky landing page and a few terribly misguided surfers who might possibly (but probably won't) click the adverts... Sorry man, but no.
