Well if you use a mac, go into your Music folder and copy the iTunes Folder.
On a PC I don't know, but I guess it should be on a similar folder.
Yes, although you may need to use special programs or softwares. :)
you cant. you have to have the music on your computer. and after that just sync it,
If you have music backups of the old iPod in iTunes, you can easily sync the songs with the new iPod. If you don't have backups, you are also able to transfer purchased songs from the old iPod to iTunes using the "Transfer Purchases" function of iTunes. You won't be allowed to transfer the songs from the old iPod to computer or new iPod if the songs are not from iTunes. This is how to transfer music from old iPod to new iPod with the "Transfer Purchases" function of iTunes: Step 1. Plug the Old iPod into computer via the USB cable. Then launch iTunes. Step 2. Click "File > Device > Transfer Purchases". iTunes will automatically transfer the songs to iTunes library. Step 3. Plug the new iPod into computer. Then import the songs from iTunes to the new iPod.
