I very definitely could have gotten everything in focus with a tripod. (This was a G2 photo, as you guessed; the G1 is pretty much a dedicated infrared camera now.)
It's 12 feet to the bottom step from where the camera was. I was just walking by, looked down, liked the photo, rested my camera on the railing and shot using P mode -- 1/20th second at f2.0.
Despite the look of the picture, there was hardly any light. A good f4.0 (even less) would have captured it all. I only took the one shot. Sometimes you shoot 60 pictures to get one and other days you shoot one and that's all you need.
Having said that, if the movers don't damage things too much, and I don't get too busy, I might try again with a tripod in Av mode.
As for sharpening, I usually torque everything down tight with a socket wrench, but I was getting a bit of halo around the the outside edge of the molding, so I backed off to 80%, 0.4 radius and 0 threshold, rather than my usual 120%. Actually, it looked even better when I used UltraSharpen at 200%, 1.0, 0, duplicated the layer, and then used Photoshop's Unsharp Mask at 120%, 0.4, 0 and set the opacity of that layer to 30%.
But, as I said, the halo was bugging me. I couldn't understand why I was getting it. So I walked over to the new house, checked out the molding and, sure enough, it was paint overlay from a not-too-perfect job of cutting in around the molding. The point being that heavier sharpening would have worked very well, except for the painter.
