You'll find a (very little) bit in this book:
Lyle Campbell and Marianne Mithun,eds., _The Languages of Native America_.
University of Texas Press, 1979.
There's a survey article by Irvine Davis on Kiowa-Tanoan, Keresan, and Zuni
with some references to (older) literature.
I also checked Vol. 9 (one of the Southwest volumes) of the
Smithsonian Handbook of NA Indians (which covers Laguna and Acoma) and
there's a little bit in there, but practically nothing about the language
except that the group has no known linguistic relatives.
Hope this helps a little.
