This is a frequently enough asked question that it should probably be
addressed briefly here again.

DY> 1) Is the define-global-key okay?

Depends on whether you happen to have that function doing the right
thing.  There is no define-global-key in GNU Emacs as distributed;
perhaps you meant global-set-key?

In order to access the rest of the binding, if you do have M-[ A
correctly bound, Emacs needs to follow key prefixes to it.  Since
backward-paragraph is still bound to M-[ it can't do that.  A
global-unset-key of M-[ will enable Emacs to look further for the A,
and hence the command to execute.

Which vt100 question?  Anyway, you can
(setq term-setup-hook 'enable-arrow-keys)
in .emacs to have the arrow keys enabled after the term/$TERM.el file
is loaded.  See emacs/lisp/term/*.el and emacs/lisp/keypad.el for more
information.
