Note that both the backspace thingy you asked before and these cursor
motions are already the default behavior.

I.e. in your case the problem is not that Emacs's key bindings do not suit
you, but that for some reason Emacs does not properly recognize the keys
you're using.

In such a case `global-set-key' is not the right answer (although it can
work).  You want to use instead:

        (define-key function-key-map [foo] [bar])

where [foo] is the key-sequence that Emacs thinks he receives and [bar] is
the corrected key sequence.  Try to hit your `right' key and then do C-h
l to see what key-sequence Emacs received when you hit `right'.  If it says
something like ESC [ 0 ~, then try

        (define-key function-key-map "\e[0~" [right])

PS: One of the differences between changing function-key-map and using
    global-set-key is that the former will also work when you use C-x right.
