Emacs / XEmacs have a very sweet octave "mode" which many of us prefer to
the ultimately fairly restrictive ides that come with software like that.

Edit ~/.octaverc and set something like

LOADPATH = [ ".:/home/mymyselfI/octave/oct//:/home/memyselfI/octave/m//:",

"It depends". Octave is more like Matlab4 so newer toolboxes will need work.
I never tried using one of their toolboxes; I am sure their copyright
prohibits it anyway.

As for third-party and academic toolboxes: quite a few, but not all, are
written for both matlab and octave. So, as I said, "it depends". I don't
know the mapping one.

Not me. 

I use GNU R more these days, and among its users are people doing spatial
stuff, and talking maps. You might want to google the ML archive at
