I think those are good suggestions to talk about with your pdoc. You aren't the first student he/she has treated. I don't think any of those accommodations are unreasonable - especially if your pdoc can attest that you have a history of symptoms which would require such accommodations.

As for the question about group work, I think your accommodation #3 might be sufficient. If there is strife in the group, you can just step out. I don't think that you will be allowed to be exempt from participating in group work entirely. One of the protocols for academic accommodations is that they do not "Weaken the academic standards of the course". If group work is a major component of the class, then you might want to rethink taking that class.

This article by the APA explains a little bit more about what to expect from academic accommodations: http://www.apa.org/pi/disability/dar...kit-three.aspx
