Video camera and firewire

I just bought a Canon Elura 100 (http://tinyurl.com/ofuhx) I’m not sure how to transfer video onto the computer. I consider myself quite tech savvy but when it comes to hardware I’m baffled. So here are the questions:

  1. How do I check if my computer has the required IEE 1394 firewire card/port?

  2. If I have a firewire card/port, where do I get the firewire cable?

  3. Can I transfer video just using the USB cable? If so why isn’t my camera being detected as a capture device?

Any information is much appreciated!
