Copyright and trademark depends on the country where you are in and the size you expect your site to reach. Copyright is granted automatically by creating unique content, but in some countries like for example the US, registering copyright has the advantage that you can claim more money if someone infringes on your copyright. Trademarking and copyright is a specialized area though and the members in the Content, Writing and Copyright forum [webmasterworld.com] might have better advice on that issue.
