Alongside Heidegger's "Being and Time", I'm reading commentary on Heidegger's work by Brad Elliott Stone including the highly recommended "Curiosity as the Thief of Wonder: An Essay on Heidegger’s Critique of the Ordinary Conception of Time" (pdf).
I'm eagerly awaiting his paper "Being and Time for the Average Da-sein". A draft version was up on his website for a while but I missed it and he's now taken it down prior to publication.
Still, it's something to look forward to.
