2. The console and speaker enclosures are pretty minor $ damage. And 3. you can probably find a door fairly cheap at a junk yard or in the classifieds here and then have it repainted to match if you're trying to save some money. But your insurance should cover the loss no matter what unless there's some major engine/suspension damage you haven't discovered yet.
Really strange about them leaving all the other stuff... maybe they got caught in the act of dismantling the car and got scared off? Anyway, good luck.
