If you want crisp (sharp) photos then the easiest way is to used fixed focal length lenses (called 'prime' lenses). Even cheap primes will take sharper photos than high-end zooms.

If you already have a 35mm f/1.8, I would suggest spending ~$120 on a 50mm f/1.8 and also buying either a 100mm or 135mm prime. The combination of those three primes should cover the focal ranges you will be snapping pictures with most of the time very nicely.

I don't know the Nikon line very well, but the D90 (or the similar, but cheaper D5000) is probably what you're looking for.
Thanks, I'll keep that in mind.
