No worries. Try this:
(defadvice maxima-send-region (before maxima-start-imaxima first)
"Ensures that imaxima is running and the correct flag is set."
(setq imaxima-use-maxima-mode-flag t)
(unless (get-buffer maxima-buffer-name)
(with-temp-buffer (imaxima))))
(ad-activate 'maxima-send-region)

I can't reproduce this exactly. When I use the advice without wrapping
the call to imaxima in a with-temp-buffer macro, I get an 'args out of
range' error--presumably because emacs is in the *maxima* buffer when
the call to maxima-send-region is called. By wrapping the call to
imaxima in a with-temp-buffer macro, I ensure that maxima-send-region is
called in the source buffer.
I am not sure if this will fix all your problems, though. To me, it
looks like comint mode is messing up input and output.
