Hi Ken
All this hammer and padding is none sense, honestly I wonder sometimes if the author of these things has ever actually done the job? Use the threaded rod method as Dave suggests, some studding from a B&Q type place, nuts and washers (lock 2 nuts together trick above the crosshead lug and long nuts on the bottom and a ratchet spanner makes life so much easier).
To your specific questions
For ease of space take damper completely off, don’t have to but makes much more room and easier to put on lock
If your just fitting springs and steering bearings disc and hub can stay in place... However, my advice is to get a pair of inner hub seals (Cain at Wolf Performance keeps stock as I sold my big bag of them to him along with the kingpin business ;-)) then pull the bearing races out, clean inspect and repack with fresh grease. You can then forget the front end other than greasing fir many years.
Just as a footnote there is no disc backplate (AKA sh*t shield) on a Morgan ;-)
