They way this is supposed to work is that the help is displayed in an
emacs overlay. See http://www.emacswiki.org/emacs/ESSAuto-complete for
screenshots of this in action.

In your case this is not working because you told emacs to use html
help by setting

'(setq inferior-ess-r-help-command "help(\"%s\", help_type=\"html\")\n")'

Yes, set the variable 'ac-use-quick-help' to 'nil'.

 Or, better, bind it to a

Yes, you can do something like

;; set long ac-quick-help-delay (don't activate automatically)
(setq ac-quick-help-delay 9999)
;; set key to call ac-quick-help manually
(define-key ac-completing-map (kbd "M-h") 'ac-quick-help)

This will still result in the help page opening in the browser, which
is not ideal. My advice would be to use the emacs R help mechanism
instead of the html one (i.e., comment out your setq
inferior-ess-r-help-command... line).

Best,
