Answer 1

Did the back and forth between PC and Mac file systems screw up my files somehow?
Yes. Unfortunately the move has almost certainly caused the loss of the resource data that would have been (invisibly) attached to those files.
By adding a specific .mov extension after the fact you will have helped the Mac correctly identify the file type / asscoiations but also significantly you will have physically changed the filename eg from "clip" to "clip.mov". This means that when you come to reconnect the media in FCP , then FCP will be looking for files that no longer exist at the given path eg when specifically looking for our example clip called "clip" of course it won't find it.
Try this as a test... first remove the ".mov" extension from one or more of the clips, select those clips and press Cmd-Opt-I to open an Info window for the selection. You'll see an "Open with:" popup and in that popup you should choose QuickTime Player (if its a Unix Executable then it will initially list Terminal as the appropriate app, you have to choose Other... then in the open dialog choose Enable > All Applications and then navigate to and select the Quicktime Player app as the appropriate app). After you've done that restart FCP and see if you can now reconnect to those clips.
