I’m sorry; I don’t know any free apps, but I can suggest two paid apps, if that’s any use.
There’s an app called Audiobook Wizard that I used a year or so ago, under Snow Leopard, that seemed reasonably fast and easy to use.
However, it’s a paid app ($4.99) offered through the Mac App Store: http://itunes.apple.com/us/app/audiobook-wizard/id460967298?mt=12. This is apparently Lion compatible and a decent audiobook editor. I haven’t tested this version though.
The developer also offers a free version, which can be downloaded from his site: http://www.audiobookwizard.com/. This only supports Snow Leopard and below, because it has PowerPC components, but you might like to download it to get a feel for the app.
There’s also Audiobook Builder. Again, this is a paid app ($5.99) in the Mac App Store: http://itunes.apple.com/us/app/audiobook-builder/id406226796?mt=12. I haven’t used this before, and I’m not sure if it’s Lion compatible. A cursory search of the forums on the developer’s website doesn’t find any problems, so it might be ok. Might be worth trying; not sure.
You’re right about .m4a
and .m4b
files. This isn’t so much a problem with iTunes, as the file types. .m4b
files have the capacity to “bookmark” parts of the file that .m4a
doesn’t. From the Wikipedia page on MPEG-4 Part 14:
Audio book and podcast files, which also contain metadata including chapter markers, images, and hyperlinks, can use the extension .m4a
, but more commonly use the .m4b
extension. An .m4a
audio file cannot "bookmark" (remember the last listening spot), whereas .m4b
extension files can.

Before you transfer your purchases, make sure that your MacBook is authorized with the same Apple ID account you used to make the purchases. And for audio books, only one download is normally allowed per purchase. You can find the answer in Apple support center.
