Hello.
Here's a quick tidbit to help the PS1 variable do the right thing depending on the terminal - X or otherwise. I've added these lines to my .bash_profile and found them useful:
case $TERM in
xterm)
export TERM=xterm-color
export PROMPT_COMMAND='echo -ne "\033]0;${USER}:${PWD/#$HOME/~}\007"'
export PS1="$ "
;;
rxvt|Eterm)
export PROMPT_COMMAND='echo -ne "\033]0;${USER}:${PWD/#$HOME/~}\007"'
export PS1="$ "
;;
linux)
export PS1="\[\033[0;32m\]\u \[\033[1;32m\]\W]\[\033[0;32m\] "
;;
esac
Sincerely, Andrew

On the same note how would you find out wether you were logged in as root or not?
Basically I want to do the same as Andrew but based on what the user was logged in as.

[ "$(id -u)" == 0 ] &&
{
# Do stuff as root
} || {
# Do stuff as normal user
}

I set my prompt to a different color based on the above.
case $UID in
0) export PS1='\[^[[40;31m\]\u@\h:\w\$ ' ;;
*) export PS1='\[^[[40;0m\]\u@\h:\w\$ ' ;;
esac
That little octothorpe just isn't enough of a warning.

Nice! That should come in useful for anyone using different types. Fortunately, they all use the same 'xterm*' entries in the .Xresources file, so other bits of behavior, etc. don't need to be adapted.
Somewhat in the same vein, I like to distinguish between consoles 1-3 by setting different colors (I also use red, but it's reserved for root logins). From my ~/.bash_profile:
TTY=`tty`
[ ${TTY:5:3} == "tty" ] && { # If not a console, bail!
color=(x blue green magenta) # tty's start at 1, arrays at 0...
setterm -foreground ${color[${TTY#*y}]} -store
}
