Help: Convert 8mm tape to dvd and edit with imovie

Please help. I would like to convert my 8 mm tapes to dvd and edit them using imovie. I have the original camcorder that captured the video and it still works. (The camcorder is a Fisher Camcorder-8 model FVC-801 circa 1987). It says digital on the camera so I think the videos may already be in some sort of digital. I also have a new macbook and it only has usb ports not firewire. To play the video on the tv the camera came with a RF Adaptor and all i do is plug the adaptor into the camera and the yellow, red, and white cords into the tv. I have done a bunch of research and it seems that I will need some sort of converter. Can someone please tell me what kind of convert, which brand I should buy, and how the process works (ie what gets plugged into what, etc) Thank You.
