My one piece of advice would be to go into a real shop that carries a decent range and handle a few cameras. What feels right in my hands might not be good for you. Take a bit of time, try working through the basic controls. At the end of the day, the best pictures come from looking carefully and being able to get the camera to do what you want before the moment has passed. The great thing about digital photography is you can see the result and have another go if the settings need tweaking. But the feel of the thing is more important than how many megapixels or modes the thing has.
