best way to sync my ipod / itunes to my new imac?

[snow patrol]

hi all, i have my ipod currently synced with my macbook, but i now want to sync it with my imac instead. What's the best way to get my library and settings / music etc onto my imac and keep it all intact and simple? Many thanks!

this is kind of frustrating cos i tried just copying the contents of my music folder over and importing into my new itunes, but i have loads of duplicates etc..
