So after we had lunch today, this is what I'm doing too. Making lists of what I need for grad school auditions, trying to figure out the fewest number of pieces I can record and still apply...
As far as French arias go, have you considered Manon? I think you'd sing a gorgeous "Je suis encor," and the other two would probably suit you as well. Also, I know you're not necessarily a straight-up coloratura, but what about "Je suis Titania" from Thomas' Mignon? Or "Il faut partir" from La Fille du Régiment (for that matter, what about "Chacun le sait"?)? You'd sing a nice "Du gai soleil," but I know there's something more exciting out there.
I think you should look at John Musto's "Recuerdo" for a contemporary English art song. It's brilliant.
