Agreed.

Yes.

lp:ubuntu/subversion is an alias for lp:ubuntu/maverick/subversion, they
are the same branch. Otherwise, yes.

Yes, and Launchpad will do this for you automatically when you push a
new ~*/ubuntu/*/subversion/* branch without being told to.

The thing to always remember about stacking is that it is *just* a
bandwidth/storage optimization. As such, it's not critical, and can
always be adjusted later. Reconfiguring the karmic branch to stack on
the lucid branch would save a bit of network I/O when pushing to the
karmic branch, but that's all.

The command to do so is:
bzr reconfigure
--stacked-on=bzr+ssh://bazaar.launchpad.net/~svn/ubuntu/lucid/subversion/ppa
lp:~svn/ubuntu/karmic/subversion/ppa

(The lp: syntax doesn't work in --option= arguments at the moment)
