[Trisquel-users] What should I remove/install to make a media center from the base Trisquel 6.0 install?

[hellocomputer8]

My objective: to create a working Trisquel 6.0 install with enough to play  
videos, view samba shares and manage files and browse the web. I could start  
by using the commands on http://www.psychocats.net/ubuntu/purelubuntu , but I  
don't really know where to start from there. How would I install a LXDE  
desktop with the Lubuntu default settings?
