Go to debian.org, download the latest netinstall iso (around 100 Mo)
No need to have bittorent, because there are lots of Debian ftps available,
since you have broadband.. Install the base system, once you've done that
use "aptitude" (read the help provided) and choose whatever you want :
X would be nice if you want to have a graphical desktop, then whatever
appeals to you...
Cheers
P S Feel free to ask more info, the Debian users here are VERY competent (not necessarily me, but others are
)
