My only comment would be Under the Lake/Before the Flood is before the Dalek occupation as they're set in 2119, and the Daleks are generally said to have invaded around the 2150s. But otherwise I think you're more or less spot on.
If I'm allowed to make a suggestion, you should move the New Series UNIT audios to before The Day of the Doctor, as Osgood still hasn't met the Doctor by UNIT: Assembled, which means this would have to be set before TDotD
