For a good site for evals, I would look at http://www.dpreview.com. He does get technical though.
One thing you would want to determine is what size of camera that you want for a point and shoot (dimensions). Determine under what conditions will be using the camera (like amount of light, do you want the lens to retract and protect itself when turning the camera off). Do you want a point and shoot that allows all the controls of an SLR? Larger cameras allow larger sensors with less noise and better light sensitivity. Lower f-stops allow more light into the camera.
