It sounds like you're using the Emacs-X11 start menu shortcut that's 
created by the X-start-menu-icons package.  Don't use it.  It doesn't 
set up the environment properly before starting emacs.  To get a useful 
shortcut, you can use the script /usr/bin/make-emacs-shortcut that comes 
with the emacs package.

This is ugly but harmless.  It's an escape sequence that's part of the 
shell prompt, which is controlled by the PS1 environment variable.  (In 
a normal shell, as opposed to one in emacs, you don't see it directly; I 
think it affects the color of the current directory, displayed as part 
of the prompt.)

Read about the PS1 environment variable in the bash manual (or google).
