The first Parade article (
Inside the Odd Mind of Hugh Laurie) is, as far as I recall, completely safe, but I didn't read the comments below, so no promises there. As a spoilerphobe myself, I just now read the second one (
Hugh Laurie Discusses Rumored Death on House), and he very briefly and vaguely discusses the theme of the rest of the season, but there's absolutely nothing specific. I consider myself pretty strict in my spoilerphobia and I don't regret reading it, so you're probably safe.
I don't know anything about the E! article, though... I'm wary of it myself, so I'm not going to read it until someone gives the all clear.
