You are copying the music to a folder on your computer somewhere. Go to prefrences>copying then see where the defualt location is. I set mine to a folder called music on my desktop. Then I copy all the music from the iPod there. Then in iTunes I go to File>Add To Library and all the folder. I would suggest not copying to a folder AND to iTunes with senuti, this will slow down the process signifigantly. Also make sure that iTunes copies all songs to the iTunes music folder. Then when you are done importing you can just delete said file on the desktop.
