Install switchdesk - it will let you change your window manager/desktop.

This is harder, as I have never had to do it. You may want to take a
look at the /etc/X11/xinit/xinitrc script. It looks like you could
create a .Xclients file in your home directory, and have it launch
xterm, or whatever program you want.

Take a look at the /etc/X11/prefdm script. This is what controls the
display manager selection. It looks like the script will accept any
display manager you set. The script also handles the case where you
do not have a display manager set.
