Just to insert my 2 kroki: _The Left Hand of Darkness_ has some fairly well structured language material, quite aside from its very fine story. Le Guin, and TLHOD in particular, is/are majorly responsible for the creation of Kash and the world they live in. Alas, the story that Kash was supposed to fit into was a poorly disguised re-run of her book. Re _Always Coming Home_, I suspect only the hard-back edition included the tape (CD?); it wasn't with the paperbk. edition, nor, IIRC, was there a glossary. At some point I'll send in a reply to the Celticonlang survey, albeit a truncated one-- I started conlanging long before Tolkien hit these shores, but gave it up for a long time, and have never used the Celtic languages as a starting point.
