You can add Diagnosing Jefferson, Labeled Autistic by Temple Grandin, Trevor Trevor? (a kid's book), And Soon Will Come The Light, There's A Boy In Here, Autism, Asperger's and Sexuality (I think it's called that), the three Laughing and Loving with Autism books, and since you have the rather condescending Oasis Guide, you might as well also add Helping A Child With Nonverbal Learning Disorder Or Asperger's Syndrome.
And there are a lot more too. I used to have a catalog with about 6 big pages of books on autism.
