At this casual level, no, it's not going to really matter. The cheap Nikon zooms that are sold to casual shooters all have the piezoelectric motor (trademarked as Silent Wave Motor by Nikon and sold as AF-S lenses, as well as Ultrasonic Motor by Canon) in the lens. Sigma also has a range of such lenses (but I cannot in good faith recommend Sigma lenses), and Tamron also is starting to update its lens lines to have standard motors in their lenses.
The main difference is that the piezoelectric motors are quiet and fairly fast. You can also manually focus them without flipping a switch on the camera body. Again, rather moot for casual shooters.
Since you sound unsure, my suggestion is to get a Nikon D40 dual lens kit. B&H is selling the kit for $650, and if you want to upgrade it's a cheap enough body to use as a backup or to sell at minimal loss. It's "only" 6 megapixels, but it's plenty enough. I'd say given the advances since the D70 it's slightly better than the D70 from a pure image quality point-of-view.
