Mister D, it sounds like yer on the right path here as to getting her right again. Looking at the pic's you posted I tend to agree that something might have happened during shipping as I can't picture that gun leaving S&W like that!! That yoke though look's definitely bent and for the life of me I can't picture just what could've done that as that's some fairly high strength steel used in the manufacture of the gun...

Please keep us posted, Good Luck, and Thanks for posting about this!!!
