i got a touch aswell yesterday and i used to have a nano. i will ask my mum seeing as she did the transfers for me and i will come back to you with an answer hopefully :)
Presumably you have your song files in iTunes?- If so, just connect your new iPod to the computer and populate it with the same songs in iTunes 'Music' section at the top of the menu.
Key functions:
1.It can backup your iPod files to computer and tranfer music/video/photos from local files to iPod without iTunes.
2.It can transfer your iPod files to iTunes and another iPod.
3.It can manage your iPod as a hard disc.
