does it need bodywork?? the color wouldnt matter if you're going to be doing any bodywork on it, since it will be covered or removed anyway. the chances are very slim the you'll be spraying right over the epoxy that's on the bare metal. And you will only need one good coat, epoxy is expensive, so it doesnt pay to waste so much on it. just make sure that ALL the rust is gone, even if you see a little spec of surface rust, it cant be there if you dont want paint problems down the road!
