1) you should expect the same kind of thing you would on any date, which is: doing something both of you enjoy doing as you get to know each other.
2) probably don't call her a crossdresser if you want to have future dates. if she's dressing, acting, and living as a woman, treat her like a woman and call her as such unless she says otherwise.
3) don't bring up her genitals or surgeries unless the conversation is going in a sexy direction anyway and you want to see her naked (if you wouldn't ask these types of questions to a cis woman, extend her the same courtesy and don't be an invasive weirdo just because you haven't knowingly interacted with someone like her, it's a date not an information panel.) safe topics of conversation are the same ones you would bring up on any date.
4) treat her like a human being with individual tastes and interests, just like you would with anyone else you're taking on a date. it feels weird to be treated like a novelty or a representative of everyone who shares just one aspect of your identity, and if you're on the receiving end of that it's usually obvious when someone is doing so. at the same time if you're nervous because you've never dated someone like her, it's better to say exactly that. do your best not to be rude, and if you make some missteps apologize quickly, correct yourself, and move on. just be nice, if the date goes well it goes well, and if it doesn't go well, no harm no foul, just no second date.
