Nice to see people getting interested to Debian

Anyways you shouldn't need to browse all the archive you linked. That's not the way to get your Debian.
Go on the main website,
www.debian.org, and download the
netinst iso in the download section. Once put on the usb device, it won't work as live system, but the bootloader makes you choose directly the options for the installation, and it will start installation process downloading all needed data from the internet.
If you want a live Debian you can refer to
http://live.debian.net, but that's useless if you just need to install it on your system.
Anyways i guess you read some documentation about the different versions of Debian. If you install the
Stable (
Wheezy at present), your software might look obsolete if you need most recent stuffs, like games and drivers, on your box. So you may need to enable backports repositories, but this can be not enough as well.
If you really want to use Debian as desktop and games and so on, you should install al least the
Testing (
Jessie as now) or
Unstable (it's called like this for its frequent updates, not because it crashes

also if updates can mess something).
If you want a feedback, I did use the previous
Stable(
Squeeze) as main os for many months and it was fine, but i had no specific necessity for latest software/hardware support. Now i'm with
Jessie and it's also very stable.
If one day you'll need a pentesting distro, then choose BackBox!

Have fun!
