Does some other channel have the xmltvid for that channel already 
specified?  If not, it's probably becaues of the --do-channel-updates 
(which you do not want if the Schedules Direct lineup is 
incorrect/outdated).  You can quickly scan through (or Find in page) the 
xmltvids for the channels in MythWeb's Channel Editor.

mythfilldatabase will never remove channels from the MythTV database.  
You must do this with mythtv-setup (in the Channel Editor, select the 
bad channel and hit D).

This is because you added --do-channel-updates , from --help:

--do-channel-updates
    When using DataDirect, ask mythfilldatabase to
    overwrite channel names, frequencies, etc. with the
    values available from the data source. This will
    override custom channel names, which is why it is
    off by default.

No.  You just need one run to update your channels database 
(--only-update-channels --do-not-filter-new-channels), then one run to 
grab data (--dd-grab-all).
