If you are a Christmas light fiend, put switched outlets under the eaves and in a few places around the outside of the house. I have three switched circuits under the eaves (front, rear, garage) controlled by Leviton relay switches, all on the same x10 address. 20 minutes before sunset HS turns everything on. I forgot to spec the ground level circuit(s) when I built, so I'm stuck with plug-in modules there. I need to run a new circuit to supply power to the fish pond, so I might run a switched lighting circuit at the same time.
Depending on how much you plan on installing automation, you can wire the house with NO 3-way (or 4-way, etc) switches, and install the loads in out of the way locations. Then install multi-button switches, (ie a KeypadLink) at the locations wher you normally would have switches. When you do this, it eliminates the "switch banks" that normally crop up around the doorways, especially exterior doors. Very versitile, and it removes a lot of visual clutter.
Look around for places that you MIGHT want electricity in the future, either for electrical appliances, or lighting. Some suggestions are near the fireplace mantle (so you don't have to string an extension cord 8 ft for xmas light on the mantle), lighting for picture frames or artwork, in cabinet lighting, etc. In one house, a structural requirement left a ledge on the wall of a mid-level stairway landing. The homeowner was going to drywall the top portion so it would be a normal flat wall. I suggested that she leave the ledge, and add receptacles on both sides. Now she has pottery on the ledge and a lighted picture above it. It always draws comments from guests, and the homeowner thinks I walk on water.
As for current code, as dublin00 mentions, an Arc-Fault interrupter is required on all bedroom receptacles. I'm not sure if an individual circuit is required for each bedroom (I always do it that way), but I believe it is. You need a individual 20 amp circuit to each bathroom (with a GFI protecting all receptacles), as well as the dining room. TWO 20 amp circuits are required in the kitchen.
As always, CHECK WITH THE LOCAL INSPECTOR! The NEC might be "national", but the implimentation and interpretation varies widely by jurisdiction. This is NOT a case were it's easier to ask for forgiveness after the fact rather than permission beforehand.
