There have already been some excellent responses with great information. I wanted to add two other little tid-bits.
For kitchen knives I strongly recommend wood handles. They are the only handles that will not slip out of your hands if they're wet.
I also strongly recommend avoiding the "never need sharpening" knives at all costs. I find they never cut evenly (one I had to hold at a constant angle to cut "straight") and they will not keep that nice edge forever. They will be sharp enough to cut - true - but there is nothing that compares to working in a kitchen with finely honed knives (yes - keep a sharpening bar handy at all times).
Lastly - and it may not have occurred to some - is getting some good heavy (restaraunt supply) spatulas and edging one side like a knife. You can be working, flipping, turning and slicing all without having to change tools.
