Adding to the suggestions above, The Disability Studies Reader can be a good place to start for disability studies. Also, Crip Theory.
If you are interested in looking at journals, GLQ had an issue on disability and queer theory, edited by Robert McRuer & Abby Wilkerson (the former edited Crip Theory. Both worth looking into)... There is also always the Disability Studies Quarterly, which covers a range of perspectives and modalities.
I do a lot of work in this area & queer theory (mostly relating to psychiatry), so feel free to message me if you are looking for more. Have fun
