Thanks for the advice. This didn't quite for me as written -- Emacs told 
me TeX-command: Invalid function: (quote TeX-run-command) when I tried 
to use it. I modified it to the following and it seems to be working 
quite well now:

(eval-after-load "tex"
  '(setq TeX-command-list
         (append TeX-command-list
                 (list
                  (list "ps2pdf" "ps2pdf %s.ps && start \"\" %s.pdf"
                    'TeX-run-command nil t :help "Generate PDF file")
))))

Aha! That makes sense. I must confess that I had looked at 'start /?', 
but did not make that connection....

Thanks for the help!
