Ana,
DAISY is very flexible in terms of what content individual books can
incorporate. For instance, some contain pre-recorded spoken audio of
the entire book. These are called full-audio books. Others may contain
only the text, which would then need to be processed by speech
synthesis software for readers to hear the book. Books can even
include a rich mix of content in multiple forms e.g. audio, pictures
and text which are synchronized to enable a rich multi-media book. For
this project, the software only plays the full-audio DAISY books (in
2.02 format). I have added a new Wiki page to the project today to try
and help you, and others, to find and copy suitable books to an
Android phone that will work with our software. The page is
http://code.google.com/p/android-daisy-epub-reader/wiki/SampleDAISYBooks
The TOC means that the book doesn't contain all the text of the book,
instead it only contains the Table Of Contents (TOC). For your
purposes I suggest you ignore these, at least if you're interested in
reading them using our software.

PS: Keep asking questions as they help me to understand how I can
improve both the documentation and the software itself.
