ADE doesn't recognize the T1. You can download library books directly on the T1 wirelessly. There is an icon called "Public Library". It asks for your location and then finds your library for you.
The new Sony software needs some fixes. The only way to stop the auto-syncing is to hit cancel really fast when it starts. It has some kind of bug that doesn't remember that you told it to sync nothing. Many people are using calibre to manage their ebook libraries. Although that doesn't help with notes which is also why I am struggling with whether to use or abandon the Sony software.
