On a resume, is it appropriate to have a "professional summary" section to start it off?

I just downloaded a word 2007 resume template and the first section says “professional summary.” I’m not sure what to put in it, let alone if this section should be on the resume, or where. Any ideas? This is my first time ever needing one of these. I haven’t had to look for a job since, well, never. My dad got me my first job when I was 16. I have just filled out applications since whenever I felt the need to change jobs.
Do I need to put everything down? I have had a few part time jobs while I have had full time jobs, and I can’t remember the contact info. I have a general idea of the jobs that I have had full time. Also, since I was fired from my last job, what should I put down for that? They weren’t very nice to me and I am pretty sure that if contacted, my immediate supervisor there would say not-so-nice things about me, with a wink and a nod to the person asking. I know that it is against the law for them to bad mouth me to an employer, but an asst. manager there described to me how they get around that. My brother said to say I was laid off.
I also do not recall the name of an immediate supervisor I had at the job I had nine years ago. what do I put?

Thank you for your time, I’m really not sure about all of this, heh.
