A more on-topic question; will Bethesda be contacting their beta testers to make sure they're actually testing and not just playing the DLC early?

I can imagine many people who are chosen might see it as an opportunity to play it through sooner rather than debug the expansion. I wonder how Beth will police it.
Bethesda is releasing a public beta with requirements based on how and how much you play the game. They aren't looking for professional testers, Q&A people, debuggers, etc.
They are looking for normal, regular, average joe Skyrim players on the 360 (the base design platform) and they are releasing the entire content in the beta itself because THEY WANT PEOPLE TO PLAY IT! The best way most all bugs in Skyrim have been found is by reports from the community, through this forum, after PLAYING the game, not "testing for bugs". All the patches and updates to the game have included fixes for bugs found by numerous thousands of people playing through the game in an infinite variety of ways. THAT is why they want lots of normal gamers to play through it, because it's the fastest, most unbiased, most intensive, and most efficient way to find bugs in an
already finished product.
Why people don't understand this concept......I have no idea.
