When working with models, you probably have fixed lighting, so I would tend to go to manual exposure, and spot meter.
Set the k10d to spot metering (under the mode dial on the top left).
Set the mode dial to M
Find something of roughly average brightness, and point the center of the lens at it, then press the green button next to the shutter release. This will set your manual exposure to what the camera program line gives.
Check the shutter speed and aperture values in the screen.
Take a shot or two, and check them carefully on the rear LCD. If they are under exposed, use either edial to add 1 stop of exposure - it's on the top LCD, and also in the finder.
Try again, and you will slowly get the hang of it. It sounds more complicated than it really is.
