This may sound a bit odd but my suggestion ( and i honestly do this my self) is to shoot in jpeg if you dont want to spend time post processing.
But when u shoot in jpeg just make sure that you use the optimal in camera settings and are accurate in terms of exposure settings.
I would also suggest you give picassa a try - even this photo of yours..you can use the sliders in picassa to increase the white i mentioned earlier.
