re-install music lib from ipod touch to computer

I see a function option in iTunes that I am hoping will do what I need. I re-installed Snow Leopard recently but my iTunes library didn't load in properly. My iPod has everything including the playlists and I want to use it to fix my computer lib. Will this option do it:



"A full back up of your iPod will be stored on this computer"



Also, it is indicated that "Your iPod has never been backed up to this computer."



I can't see how to put the screen shot in that I took. The image insert wants a URL but it's on my desktop not the internet.



I have iTunes 11.4 and an iPod Touch version 6.1.3



Thanks.
