Welcome to the Nikon forum. You are smart to buy a D80. I absolutely love this camera and it is pushing me to abandon slide film once and for all (well not really, I just won't shoot it nearly as often).
I would recommend the two lens option to you. I have the 18-70mm and the Tokina 12-24mm and use them both frequently. Also, I've not noticed a dust problem so far on the D80 sensor compared to my old D70s, which had dust on it from day one (or so it seemed!).
Of course, if you would like the VR function, the 18-200mm is a nice lens. But it feels rather big to me, and I much prefer the size and handling of the 18-70mm for a general walkaround lens with the D80. And the Tokina 12-24mm is a real gem, it has been a must for me.
