I don't think so.  Someone(TM) should back-port the DOS code that
supports menus of a text-only terminal to the rest of Emacs platforms.

You could redefine mode-line-format to do that, but it will need a bit
of Lisp programming.

See tty-colors.el for the infrastructure and term/xterm.el for an
example of using it.  Actually, since you seem to be using a 256-color
xterm, Emacs should have done this automatically for you.  Perhaps you
have an old version of Emacs, in which case upgrade.

See indent-tabs-mode and tab-width.

Suggest to upgrade to Emacs 23.3, the latest official release.
