I did a search on google for you and found out that your camera also has a Firewire in/output. This is to be preferred when transferring digital video from camcorder to PC. Therefore, I strongly suggest that you try to connect your camera to PC with a Firewire connection instead of USB. If your PC is fairly new, chances are high that it has a Firewire port built into the motherboard already. If it doesn't, you can pick up a 10$ Firewire card and put it into a free PCI slot into your PC.
From that moment on, you can use any software that is able to record digital video through Firewire; even Windows Movie Maker, but I would recommend Adobe Premiere Elements if you're just getting started or Adobe Premiere Pro if you're becomming more experienced.
Keep in mind though, that for smooth video-capturing, it is very important to have a harddrive capable of a sustained datarate high enough to capture video. Theoretically, DV-avi (the format in which you will probably capture your video), is 3.6 MB/sec, so you might think that any harrdrive is capable of doing this. Well, it's not Harddrives that are too fragmented (lots of small files spread all over the drive instead of nicely put after each other), will decrease recording speed dramatically and result in dropped frames (meaning you don't capture 25 frames per second). You don't want dropped frames by the way, as this will result in sound being out of sync with video.
Therefore, I suggest that you keep a dedicated drive only for capturing the video.
