Apologies for jumping in without the whole context (I'm buried with work
and I have not been able to even read the whole thread). I'm not sure
how to do #1 and #3 above, but I believe that #2 can be done with the
mapping API (see section A.10 of the org manual) - something like this
(untested and too simple as it stands - probably won't handle headlines
without a todo keyword correctly):

(org-map-entries (lambda () (org-todo "TODO")) t 'tree)

but it may be worth a try. It may even be possible to extend it to do
the other stuff.

HTH,
Nick
