I guess I didn't see the mask as being the 'new' mask when I read it; it just looked like a more modern artistic interpretation of the original (the new mask having the more obvious points at the top corners). And Ivan Reis did take the care to depict Hal in his original costume (with the 'tank top' style of the green torso of the uniform, going straight up instead of coming down to points on the shoulders).
As far as Tom/Pieface, well, it's true that the Pieface nickname has long since gone by the wayside, but it is a bit of a retcon to not have Hal call him that in the early days. It's just a matter of what was acceptable in 1959 vs. what's acceptable in 2008. Fifty years ago the heroic Great White Protagonist could affectionately use a mild racial epithet for his sidekick's nickname. In the modern cutural climate, such an action would not be suitably heroic, I suppose. I give Geoff Johns points for addressing the issue, as a matter of paying homage to the past, and then moving past it.
I liked the story overall. I think the only element of the original that I missed was Hal being pulled to Abin Sur's crash site in the flightless trainer/simulator (here Hal is simply pulled bodily through the air by the power beam). I'm not going to go fanboy-insane and cry out that Geoff Johns raped my childhood or whatever, but to me the shock Hal experiences when he realizes he's flying in a flightless trainer was kind of a key element of the sense of wonder to that origin story. I miss that element, but the story as a whole still has enough going on to keep me entertained.
