No you don't. As long as the iPad is plugged in to the computer and iTunes is open, the document automatically appears in the iTunes sharing pane. If you want the document on the computer you then grab the document from the iTunes sharing window and drag it out.
That is just my problem. Pages documents are not appearing in the Pages Sharing area in iTunes. They did at one time but they dont now. I have recently cone back to using Pages so to have this facility would be useful.
