You should definetely have Van Eyes even if you have rear view camera. The camera usually turns on when you shift in reverse, but van eyes along with your rear view mirror will help you have a better rear view. It's not called van eyes in the store (at least mine didn't), but it's basically a plastic wide angle lense you stick on the inside of your rear window.
As to the camera, there's plenty of them out there, it's usually the monitor that makes the difference: most people have the indash one, that's also connected to the DVD player, GPS, etc. That's installed instead of the stock head unit. Search this site and club.vmag.com for more samples.
Or you can use rear mirror built-in montor. I have this one: http://www.savv.com/rear.htm
Welcome, and have fun modding!
