iTunes help!

[�mermaid�]

There are a number of things about iTunes puzzling me!

>>How do you transferr music from an iPod to itunes, as I've just got a new computer? Apparently it's quite complicated and you need special equipment?

>>When you add artwork for music why does it only appear for the song that was playing when you dragged and droped the image? Is there a way of adding the same artwork for a whole album?

>>When you have added artwork for a song is there any way of deleting/replacing it? I've tried to drag another picture onto it but this doesn't work?

Also is there any kind of decent iPod/iTunes guide which answers this kind of stuff? Thanks =)

As for the artwork, iTunes can grab it for you automatically. Advanced->get album artwork. This requires you to have an iTunes Music Store account (free), but it goes through all your music and adds albums for everything it can.
