Thanks Shawn. I still have trouble with the pushing of the center button. I often want to advance the story and end up mostly with the sound adjustment. That is how the speed got "off". I could see how to do it under audiobook settings, but thought it might be a slider bar under the Now Playing section.
Shreyas - someone more knowledgable than me can help you better, but I just add the book to the library of iTunes and then sync the ipod to it. I just use add to library I think. Good luck.
