To share or not to share (your student evals)?
Where I worked in Germany, faculty were required to share the statistical results of the survey with their classes, and allow for time for feedback. So I see no issues in sharing results when no student-specific data would be given away. (Note that the surveys thus effectively represented "midterm" evaluations.)

As far as comments, that's a bit trickier. I'd err on the side of leaving out anything that talks about the student instead of about the class. 


  I think that X 


would be fine, but


  Because I transferred and hadn't studied Y at my old university, this class was very hard


would not, since it might give away some information as to who said it. You could present a redacted version:


  Because I . . . hadn't studied Y[,] this class was very hard


if you want to remove anything identifying individuals.
