(defun testfun1 ()
  (interactive)
  (setq a '(0 0))
  (print a))

The expresion '(0 0) builds a list when you're defining testfun1. That
list is being modified by testfun2().

If you use

 (setq a (list 0 0))

you build a new list every time that testfun1 is executed.

Take a look at the Emacs Lisp Introduction and the Emacs Lisp
Reference; they're bundled with Emacs 22 (C-h I to access the Info
Directory).
