how much paint do I need??
If you are still have the factory paint, then typically a sealer isn't required. Without any pictures, it is hard to judge the condition of your actual car. You could possible get away with sanding clear then painting new. It could also be worse damage.
You should paint the jambs, it will look half a$$ed is you leave them shiny.
You can probably get away with just a gallon of paint. Make sure you get the correct activator for you temperature. Check out Eastwood.
