I was raised in the post-Vatican II Roman Catholic Church. One interesting thing about my hometown is that there are different kinds of Catholics (Roman, Maronite, Ukrainian) and Orthodox (Greek, Russian, Syrian). I started visiting parishes and found that I enjoyed going to a Tridentine Mass every once in a while. My wife and I belong to a "regular" Roman Catholic parish and enjoy it very much.
If you feel the seed of something spiritual inside, try to find where you feel most comfortable. For me, it was in the Catholic Church (see avatar). I have Jewish friends who are quite happy in their faith, and one of them is a convert from a family of nominal Christians.
As far as church being not AS-friendly, I think it depends on the particular worship style and such. I have been to Masses which drove me out of mind from boredom or noise or just plain ugliness. My parish avoids those problems for the most part, so I feel comfortable there. The Tridentine Mass might be pretty good for Catholic aspies; it's very quiet, you do not have to speak at all, and most attendees are nonconformist by their very participation.
SELF-INDULGENT STORY ALERT: When I was a teenager, my family lived in a housing project, but I had a full scholarship to a prep school, where I continued my study of classical languages. One day, two members of a religious group came to the door and asked if I wanted to learn about the Bible. I excused myself and fetched my copies of the Greek New Testament and the Vulgate Latin translation. The evangelists' faces looked something like this:
It was a very short meeting.
