Hi, welcome to Apple Discussions.
Are you certain you're getting duplicate track on the iPod, or is it just copying them over again? iTunes manages the transfers whether auto-syncing or manually managing not the iPod. When you manually manage you know best - if you drag on a bunch of tracks iTunes will just do as it's told, replacing exisiting copies with new ones if that's what you tell it to do. It's actually much easier to sync with selected playlists. If you update a playlist or some information about a track this will be automatically reflected next time you sync.
