According to http://ergoemacs.org/emacs/elisp_universal_argument.html
the universal argument corresponds to an argument '(4). So you could
try:

#+begin_src emacs-lisp
(global-set-key
 (kbd "<f8>")
 (lambda ()
   (interactive)
   (org-tree-to-indirect-buffer '(4))))
#+end_src

The buffer name is set by the function `org-get-indirect-buffer'.
You could try to change the name after calling the function … for
instance by doing
#+begin_src emacs-lisp
(rename-buffer (org-get-heading) t)
#+end_src
(the t at the end makes sure the name is unique), but for this to work
you need to go to the buffer that was just created, and I don't know how
to do that.
