Well, I just read these books last week. I agree with the assessments here. Here are a few of the things I took from the book.
Kvothe is of the Lackless line.
Naming is involved in the frame where Kvothe seems fundamentally different.
The door in the archives is connected with the Lackless thread.
There is something connecting the moon, the chandrian, and the Lackless.
Rough theories on my part, showing a reread is foretold in the near future.
