I have read the Russel Holtz books for flight instructing. Anyone recommend a good written test prep book or series for Glider Flight instructor written exam?

With any of the FAA tests, I have had great success with online practice
test sites. Naturally I read the material first, but then I take
multiple practice tests until I consistently score well above 90.

Such as: http://www.webexams.com/exam/view?exam=182

Especially for CFI, you can expect your oral to be a much more relaxed
event if you score high on your written. First that likely means that
you have a good grasp of the material, but also because your examiner
will have a record of the questions you missed, and WILL hit those on
your oral.

Also, for CFI you should be acquiring a mini-reference library, which
you will bring to your oral. You won't be expected to be able to answer
every question the examiner asks, but you should be able to find the
information for him/her. Ideally you will have your FAR-AIM tabbed and
highlighted for quick access.
