No need to strain your poor muscles' limited mental ressources :)
I think the following should do (added somehwere at the front of your .emacs),
either without prefix matching:
(define-key comint-mode-map (kbd "<up>")
(define-key comint-mode-map (kbd "<down>")
or, I think handier, with:
(define-key comint-mode-map (kbd "<up>") ; (I bind that to M-p)
(define-key comint-mode-map (kbd "<next>")
