Only if you're an optimist.  It's a rare day one can migrate that many
releases without some changes in config file syntax or interpretation.

You could.  Your users would get (optimistically) momentarily
disconnected.  The windows offline files balloon pops up or a message
"no longer connected to ...".

Probably.  I know some of the defaults have changed, but I don't have a
list handy.

Shouldn't, but someone else would have to say definitively.  I've
personally wiped and reinitialized most of them several times only
keeping the private tdb files secrets & passdb while regenerating the
printer tdb's and mappings.

If it's at all possible, your best course is to setup a test machine
(real or virtual) and test the new version in your current setup by
joining it to your domain and connecting from users.  Alternatively,
duplicate the existing OS & samba version with a different machine name
and perform the upgrade on it.  Your experience doing that is the only
real way to self answer some of your questions and make the production
upgrade as smooth as possible.
