with the rust, probably best off accepting that its there, you just might be lucky enough to have less than others (including myself) haha
that section above the door, best off when repairing it to remove the chrome trim, as you'll most likely find that its at the top of the door in the corner as well..
you'll also might find some in around the rear tail lights but yours seems pretty good..
not sure about the tinted tail lights, but the colours great and with some time love and care (and coin $$) the car will come looking sweet,
