I came to some of those conclusions myself, but it's always nice to have the opinion of someone outside the situation. I don't believe there would be any carpet issues here; one room is wood tile, and I believe there is enough room at the bottom of the other door above the carpet to allow for movement. I wasn't too thrilled about shaving the doors, either, so I'll experiment with the hinge first, especially since it will require such a small adjustment. Together with correcting the drainage issue, it looks like it should be ok. Thanks again for the input...!
