Joe, What was the full warning message about the normalized/laundered field name? Field name is modified when the name is longer than 10 characters or when a field with same name exists. Check the name of the newly created field.
As per the update command, I don't think the update command is implemented in the ogr sql yet. You can do it in the sqlite format, among other rdbms formats. Use ogr2ogr to convert it to sqlite. update it. convert it back to shapefile.
