Yes and yes. You are generally allowed to bring an immigration attorney with you to your interview. An attorney may make certain comments and provide documentation to the officer in some situations. Different offices handle this differently, but the general rule is that immigrants are allowed to have counsel at these interviews.

You should definately have an attorney representing you throughout the process, not just attending your naturalization interview. There can be many potential issues that can affect your eligibility and the appropriate timing for filing of a naturalization petition.
