OK so I have that large Hard Drive and I've moved all my windows files onto it and I want to start using the Mac for "all" my normal stuff! (No I can't play FarCry on it!) and having still not found out about all my photo tags, my fault not being that persistent on finding the answer yet, I now want to move my iTunes music well it seems a little more straight forward, but I want to keep all those playlists and metadata play count etc, I do already keep the library external so it seems to be a painless method, but I'll let you know how it goes. OK a small update guess what yes I cheated, I have all of my music on a seperate drive through my PC machine, so I backed it all up to the 500 gb hd I got for the Mac, copied across the iTunes library, and XML files across, along with the Album Artwork etc, I then imported all that into iTunes on the Mac, copied the xml across, and although it didn't do all the work, I still have to locate a few of the files, all of the counts and rating's have come across. I do not recomend doing this unless your a little computer savvy and don't mind doing a bi of work updating atferwards. There are methods to do it so it does all the work for you, but you have to be a little meticulous with them.
