Starting points
Try / Install Debian
Boot a 32-bit Live CD and installer (GNOME desktop): Debian 6 (stable, aka Squeeze) / Debian 7 (testing, aka Wheezy)
Other versions, types and sizes of installers (including 64 bit, net installers, etc.) are available.
If you need 64 bit versions, keep in mind Itanium is a different platform than amd64 which is most common in modern laptops and desktops.
Get a multi-arch (32 and 64 bit) installer ISO now: Debian 6 / Debian 7
Find out more about http://www.debian.org/releases/, including community support cycles, release/EOL dates, repositories, etc.

Utnubu is Ubuntu spelled backwards. One of Ubuntu's activities is frequently redistributing packages originally from Debian to Ubuntu's users. Well, Utnubu is about the reverse, copying packages from Ubuntu to Debian.
