Again, customize org-link-frame-setup, and set
the `file' entry to `find-file'.

There is nothing for this.  I guess you could insert a
function in change-major-mode-hook or so, when you get
there through linking, `old-buffer' will contain the
buffer where the link was called.  However, you need to
be careful here because this function will be called
in many other occasions as well.
So something like

(when (and (eq this-command 'org-open-at-point)
            (boundp 'old-buffer)
            (equal (point-min) (point-max))
           ......

... and maybe even more precautions...
