How about

(defun buffer-exists-p (b) (and (get-buffer b) t))

[if you don't need a 't' return, just
  (fset 'buffer-exists-p 'get-buffer)
is enough]

| (defun pop-up-buffer (b)

|    (let ((c (current-buffer)))
|       (pop-to-buffer b)
|       (pop-to-buffer c)))

How about

(defun pop-up-buffer (b) (display-buffer b t))

From my experience, I have found that GNU Emacs has *most* of what you
want already included... it just takes a little horsin' around to find
it.  I'm waiting for the EMACS-Lisp manual... I hope it helps.
