RE: Anyone have a 'move-line' function?

I think the transpose-line command may be what you're looking for.

It is bound to C-x C-t.

Exchange current line and previous line, leaving point after both.
With argument ARG, takes previous line and moves it past ARG lines.
With argument 0, interchanges line point is in with line mark is in.

Here's a solution that doesn't add to the kill-ring (not that we'll
reach the kill ring limit :-)

(defun move-line-up (&optional n)
  "Moves current line up leaving point in place.  With a prefix
argument, moves up N lines."
  (interactive "p")
  (if (null n) (setq n 1))
  (let ((col (current-column)))
    (beginning-of-line)
    (next-line 1)
    (transpose-lines (- n))
    (previous-line 1)
    (forward-char col)))
