When doing things like that with the window manager I usually start a
terminal first. I like xterm. Then in xterm I would kill the
previous window manager and then start the second.
$ ps -e | grep openbox
$ kill $OPENBOXPID
$ xmonad &
More pedantically that last should probably be:
$ nohup xmonad </dev/null >~/.xsession-errors 2>&1 &

Looks reasonable.

Looks good.

Right. Because openbox has the highest priority of any package
installed providing that alternative.
But see where it says this:
> root@dalton:/home/peter# update-alternatives --display x-window-manager
> x-window-manager - manual mode
^^^^^^^^^^^
So the priority doesn't matter and the "best" doesn't matter.
> link currently points to /usr/bin/xmonad
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
So you successfully switched the symlink.
To return the selection to the package priorities use --auto like
this:
update-alternatives --auto x-window-manager
Note that there is x-window-manager and x-session-manager and they are
used for slightly different purposes in the scripts. Both are Debian
specific because they were created to be something that the packages
could use to symlink through the alternatives so that different
packages could be swapped in and out as they are installed and removed.
