That's right, look at each part that needs to be repaired and work on it, one piece at a time. I would take off all parts that need repair and take each sheetmetal part, one at a time to a body shop (try to find one with an older man there that understands how to straighten heavier sheetmetal. If they say, "it can't be done, buy a new piece", take it somewhere else. You should be able to find an old guy that will take on the job. Remember, one piece at a time, they are more likely to help you if you don't overwhelm them.
