I agree with the comments regarding the 18-55's price tag. It's cheap enough to buy the kit and play around for a while without worrying about upgrade paths. With the advice from the Nikonian posters, I'm leaning towards keeping it simple and buying one of the kits for starters. I hadn't seen the 2 lens kit, and I agree with Moto that's probably a better option than the 18-105, since I'd be getting more range for the same price aprox.
I'm really excited about going into ultra-wide and macro shooting, but I can make those specialized purchases later on, and start thinking about upgrade paths once I get there.
