Thanks everybody. After consulting with several folks, I've decided a sleeve is definitely not a good idea - too easy to lose track of. I am still toying with the idea of making jewel boxes for radio use, but on the other hand, the book would stand out nicely (and is sized to still fit on a shelf of CDs). Track times, while not on the outside cover of the book, will be on the page next to the CD sleeve and printed on the CD itself.

I will probably send it with a little piece of paper with biographical information, etc. That stuff is in the book, but harder to find.

The book itself is focused more on ideas than music, but on the other hand, that's part of what makes the project unique.
