If you've downloaded it on your Ipod you would just need to open iTunes software with your iPod connected and select the tab audio books and tick the box to sync with your computer.
If you've downloaded a audiobook outside of iTunes and want to add to iTunes, click on File, select "add file to library", and when the open file box appears, navigate to the relevent folder where you have stored the book, and select it. I've found it will automatically place it into the audiobooks tab from there. (I'm using the latest version of iTunes)
I can't be sure on the the last part, I would of thought they would be in order anyway. Perhaps someone else may be able to help if this isn't the case.
