A topic like this was started last year as well:
Personally, I don't see myself reading many classical theoretical works before graduate school. I will probably read a few, as I don't think I got the best theoretical training in undergrad (as we read Ritzer's contemporary theory book and Coser's classical one - but no main text and such); however, I think we will get enough of this type of reading once we are in grad school.
My last few months of reading will be books in my field of interest - mainly sexuality, gender, transgender studies, and such. I just finished The Sexuality of Migration by Lionel Cantu, and at the moment, I'm reading Out of the Closets by Laud Humphrey, Imagining Transgender by David Valentine, and Unlimited Intimacy by Tim Dean.
