This seems to have worked. For future readers, here's a summary of what I ultimately did:

1) Kicked everyone out and took a backup of the database

2) Deleted the batch entirely from SY00500.

3) Deleted from PM10000 the three documents that had made it into PM20000 already.

4) Confirmed that in PM00400 the DCSTATUS for those three documents was set to 2.

5) Deleted the one document that was only in PM1000. I deleted it in both PM1000 and PM00400.

After that, the messed up batch was gone, and we were able to void or apply the three open documents left sitting in PM2000.

Thanks again for the help!
