This would be my dead simple, can't go wrong setup for the D40 D40 body (obviously) SB400 flash (it's super light and small, will bounce off the ceiling for nice indoor family shots, and still has enough oomph to use as fill flash outside) 35mm f1.8 DX lens. This is Nikon's new lens specifically for the D40. It should be very fast for indoor use and at 35mm is a more useful size than the 50mm mentioned above. Also, unlike the 50mms, the 35 will autofocus on the D40. For super simple photography, switch from the Auto mode to P(rogram) mode. As default, the only thing in this mode that is different than Auto is that you get to choose the flash on or off. That way if you need to shoot without flash inside, or with flash outside you can do it. Then, from within this mode, when you are feeling more adventurous, you can start playing with things like exposure compensation, white balance, and slow sync flash.
