visual, media, gender, sexuality theory and criticism?

hi all,
i got assigned to teach a special topics class this fall 2008. i'd like to use any sources that you all think might work well, since many of you have expertise in some of the areas i'll be covering. please pass on any helpful cites! thanks... ~ jamie

fyi, the title of my course is: "Visual and Mediated Rhetorics of Gender and Sexuality.”

lessl needed a quick description of my course to publicize to the undergards, so here's a quick explication of it: "This course will survey types of media theory and criticism within and outside of the discipline of rhetoric. Extra attention will be given to the visual medium and the mediation of gender and sexuality. The purpose of the course is to introduce students to theoretical perspectives as well as case studies in order to enhance their ability to critically see, think, write, or in other ways create better rhetorical artifacts for heterosexual women and men and LGBTQ communities. This course is reading and writing intensive as well as it is heavy in discussion."
