ESS has more font-locking (syntax highlighting) than what you see;
unless you are wedded to Aquamacs, have you tried the version of Emacs
built by Vincent Goulet: 
  http://vgoulet.act.ulaval.ca/en/ressources/emacs/mac 

this should work nicely.

sure, this falls into the general issue of rebinding keys; e.g. 

(defun my-ess-hook ()
  "Add my keybindings to ESS mode."
  (local-set-key (kbd "C-j") 'ess-eval-line-and-step)
  )
(add-hook 'ess-mode-hook 'my-ess-hook) 

change C-j and the function you want to sit on there accordingly.
 


I'll leave others to fill in 2 and 4!
