Downloading with a
torrent
is actually very simple. You just need a rightly set torrent client
(setting your connection speed is usually all you need to set). Then
you open the torrent file inside your client, set a place where you
want to download desired files and then just wait till it's downloaded.
Downloading with a torrent is no more complicated than using any other
p2p application, but even simpler.
My Favorite software and I recommend it for its simplicity and lightness on your internet service is:

Utorrent
http://www.utorrent.com/
- download it (around 200- 300 kb)
- install
- and then open the torrent files(few kilobits) that you will download from torrent subject's page
- then the software will start downloading the file.
