You've got it backwards and upside down. Make your game first, then deal with these things at the end of the process. You don't need a name, company, copyright, trademark, fees, domain -- none of it. Your planned name is not special, and besides you're not allowed to arbitrarily reserve a name forever. Doesn't even help you without a lawyer. It would be equally as effective to go to Kinkos and print off a gigantic sign with your imagined company name on it.
Make your damn game first.
