itunes is the apple download and synch site. You get a disk with your ipod for When you first plug your ipod in your pc that takes you to itunes. From there you can download (not free but cheap) make playlists etc. Most free downloads are illegal unless you subscribe to a legit site that lets you download a certain limit.
You can plug into your pc to charge up or buy a seperate 'dock'.
Sometimes you will have to put the disc back in your pc to reset when probs occur.
itunes updates regularly, you just click install
Hope this helps :)
we've all got nano's....
