Put the following in your .emacs:

(global-set-key "\C-x\C-p" 'bury-buffer)
(global-set-key "\C-x\C-n" 'yic-next-buffer)
(global-set-key "\C-x\C-o" 'yic-other-buffer)
(global-set-key "\C-x\C-k" 'yic-kill-current-buffer)

(defun yic-next-buffer ()
  "Switch to previous buffer in current window."
  (interactive)
  (switch-to-buffer (car (reverse (buffer-list)))))

(defun yic-other-buffer ()
  "Switch to the other buffer (2nd in list-buffer) in current window."
  (interactive)
  (switch-to-buffer (other-buffer)))

(defun yic-kill-current-buffer ()
  "Kill current buffer."
  (interactive)
  (kill-buffer (current-buffer)))

;; end

Note:

'bury-buffer is the primitive that cycles through the buffers in one
   direction (while ignoring insignificant buffers)

'yic-next-buffer is a simple function to cycle through the other way.  It
   even displays buffers that are usually ignored, since I don't bother to
   check them.

'yic-other-buffer changes to the default other buffer, without waiting for a
   RET

'yic-kill-current-buffer kills current buffer.

I use these all the time to move back and forth between buffers, and also the
ability to kill buffers easily is great when I am in dired-mode.

Hope this helps.
