Looking for Information

Hello,
Well recently I was "promoted" so to speak, more of just a title change to group/company owner of Iron Genesis. Now I myself have never looked into the information required to know when starting, and maintaining a company but as far as I know there are a few main points. Copy Rights, trademarks, and taxes. I was curios if anyone had some insight as where to start looking into the general information required before I take our group from just that to a company. I hope this doesn't sound at all confusing and I don't mind any advice on the subject at hand either.
