I actually have a stickied thread in the help section (link) that has some beginner's information on sex, gender, gender roles and expression, and gives links to places that explain more things! If the community wants that section to be expanded I'd be happy to bulk up that section!
edit: I'm in the process of writing a new section specifically addressing basic trans concepts and some links to info about medical transition it'll take a while to go up tho!
