In the recent issue of Cook's Illustrated, there is an Illustrated Guide to Kitchen Knives, and it's quite handy.
We agree that if you need any knives, it's a chef's knife, a paring knife, and a bread knife. Cook's breaks down each of these and gives their pick for the best buy. They also talk about sharpening, how to grip a knife, and basic knife skills such as carving and mincing.
