Scared of Conference Calls

I’ve been asked to do a conference call for a Reporter position in California. I’ve never done a conference call and to be quite honest I’m a little bit nervous about it. How am I going to survive a full hour of the typical, “Tell me a little bit about yourself” and “Why would you be good for the position” questions? What are the key questions I should be asking?
I’m sure I should research the company before the interview. I do know that it is a web-based business. I can assume that working as a reporter for a web-based business probably means I’d be working from home, right? If I am unable to work “on the field,” as they say, I am definitely not going to be one hundred percent happy. Oh well. Who is one hundred percent happy at their job anymore? I’m guessing the only way to really prepare for this phone interview is to research the position and the company as much as I can. If there is any other specific advice I need to know, I’m all ears!
