Do you have a copy of Words of My Perfect Teacher and a copy of The Wish Fulfilling Jewel by Dilgo Khyentse?
Yes, I have "The Words of My Perfect Teacher" and I've just begun to read it.
No, I don't have that book by Khyentse Rinpoche, but I'm not doing Guru Yoga yet, so I don't think I need it quite yet, although I treasure anything which Khyentse Rinpoche wrote. I just finished reading "The Heart Treasure of the Englightened Ones" which is also a text by Patrul Rinpoche with Khyentse Rinpoche's commentary.
I feel that reading Khyentse's books and watching his videos also helped me create a connection with the Nyingma school. One day, in my former Kagyu sangha's gift shop, I just "by chance" saw a copy of "The Heart Treasure of the Englightened Ones" on the shelf, bought it, and was greatly moved and inspired by it.
Any contact with the writings of Patrul Rinpoche or Khyentse Rinpoche is a great blessing.
