Does the camera have a FireWire (may be marked iLink or DV terminal). If so you should be able to hook it straight up to any FireWire Mac and use iMovie to capture and edit the video. When you find your needs are not met by iMovie there is Final Cut Express (currently cheap with a new Mac in the UK at least) and above there Final Cut Pro.
Note that many cameras not listed by Apple as compatible work fine (I just got a Panasonic NV-GS1 from eBay this morning and it works whilst not being listed).
You don't say where you are but if you head over to an Apple Store or a reseller they can probably give you advice/let you try your camera out on a Mac.
