You're assuming that --eval will loop.  If that had been the case, it
would have been called --eval-loop.  Instead it is called --eval, and
therefore it only does that.

When you want to group several expressionsions in a sequence, you must
use prog1, prog2 or in general, progn:

   emacs  --eval '(progn (shell) (rename-buffer "shell"))'

But since  you don't pass -q, emacs will read your ~/.emacs, so you
can as well put there a function such as:

(defun shell-and-rename (name)
   (interactive "sName: ")
   (shell)
   (rename-buffer name))

and then:

   emacs --eval '(shell-and-rename "shell")'
