Help on paint job please

I have decided to paint my car myself and am lost on where to start. There is some corrosion, and paint is chipping away. The whole body needs to be painted and I am changing the color......Any help would be appreciated.

sand down those tough corrosion spots, get some bondo and seal up those areas that are rusted, AFTER you have sanded the entire body down. When your sanding, it's best to do it by hand that way, you won't rub off to much to where you scratch the metal and now your paint won't stay and you'll have a hard time trying to get a clearcoat finish.
