Your camera should've come with some DV software, probably either Pinnacle Studio, or Ulead. Possibly even Premier LE.
And yeah, you'll need a firewire port/card, just make sure you look at the camera to see if it has the bigger "three story house" connector, or if it's the smaller rectangular connector. More than likely it'll have the smaller connector, while your firewire port/card will be the larger connector, so you'll need to get a cable with the different connectors on each end.
