For the notes you could use this addon:
http://www.esoui.com/downloads/info1105-Notebook.html
Talk to the addon dev if it's possible to insert something like a link to a book. Maybe it is doable.
About your other request with the note directly inside the book, I'm not sure if this would be doable.
Maybe if one can read the current book and current book's page, and open the book directly at this page by the help of the API.
