Just picked up "The Crystal and The Way of Light" from our dharma centre's a library. A book about Dzogchen - the writer is Chogyal Namkhai Norbu. I don't think ChNN is against books-even Buddhist books. I watched an interview with him in Hong Kong recently where he praised the Chinese people\s interest in and study of Buddhism.
In terms of your own personal spiritual journey, if you are honestly at a point where you think you are ready to leave those things behind for greater depth in your meditation practice, I am of course in no position to discourage you. It sounds like this journey has been well-thought out. My comments were generally pointing out that in spiritual life we have many "end-points" feeling that we have finally come to the end of our searching, and inquiry and are ready to just focus.
The thing is though, even those points in our spiritual life are still subject to the reality that we call impermanence. So the "final conclusion" might not be as final as one might think. As I mentioned before, just look at the various journeys of all the people on this forum.
These are admittedly words from a gradualist who knows nothing about Dzogchen, though, so take them with a grain of salt!
A foolish man proclaims his qualifications,
A wise man keeps them secret within.
A straw floats on the surface of water,
But a precious gem placed upon it sinks to the depths
