As long as the PDF being imported is different in any way, I always see the conflict dialog which asks how I want to handle the conflict. If the PDF is identical, then it's either ignored or a duplicate song is created depending on that dropdown selection. If you are not seeing the conflict dialog even when importing a PDF that has different content but the same name as an existing PDF in the library, then something is not working the way it should, but I would more details to explain why that's happening.
SortTitle is not currently a supported field - that's something that would have to be added. The batch import should work identically to just using one of the other import options like Import->Local File, as they both use the same underlying code. You cannot update metadata for an existing song by just reimporting the PDF again - that's not currently supported, so if you are trying to do that, it won't work. You'd have to delete the song first, then reimport. Alternatively, update the PDF, then use the option in the song editor to extract the metadata from the PDF again.
