Nice shoes. It's good to see her out of costume for once.

...By that I mean without being in her birthday suit, deepthroating 9 inches of male anatomy.

Can someone confirm my translations?

I think it's ハジメテノオト, actually (see http://www.nicovideo.jp/watch/sm1274898).
Also, なんということでしょう (and variants, such as なんてことだ) does not express uncertainty about the nature of something, but horror and negative surprise. I'm not sure if there's an English equivalent that is close to the letter, but the meaning is something like "That's terrible!"
