Importing Media

Hello, I have a video that I'd like to import shot RAW on the RED camera at a 16x9. What are the basic "master settings" and "image scaling" options to ensure that I am not degrading any of the media quality. As it is now, I have black bars above and below my footage, so I assume that the image size is not set up properly. I also want to export the footage so that the exported .mov is as hi-res as possible. Please help!
