I second what James B Lenze says. I love 'Join Together.' It's way better having the tracks of an audio book joined up, as it means your place is saved in the book as a whole; you don't have to remember which track you are up to. It can even save the track marks, but as 'Chapters' rather than tracks. It makes a collection of audiobooks much more managable to just have them all as one track.
Also, 'Join Together' can do what you all want, i.e. make the audiobooks show up in the correct section of your library.
Plus, it's free and pretty easy to use. Here's some more info about it:

You'll need to download it and read the read me to really get how it works. You just have to put a bit of time in on this one I'm afraid. It seems lots of people are confused about this, and think just changing the genre should put audiobooks in their correct place, but it's much more complicated than that.
