I'm not sure about the D7 - we saw that in the last film's Kobayashi Maru test, and Kre-o are releasing a Nero figure and Jellyfish and Kelvin models. Although I guess since they've kept the visual aesthetic so faithfully from STXI, it may well be reused or only slightly modified. The BoP we saw in the trailer. It looks more like a small fighter than a proper starship.
And yeah, I'm thinking that IS Uhura, and it's the lighting making her look white with an orange uni, instead of black with red.
