I rarely use iPhoto except for testing but it will do quite a lot if you dig around.
Duplicate an image and play with the duplicate, you can't break anything and you can always revert to the original at any time.
Look at the settings in the second screen shot, try adjusting the White balance further to blue. Adjust the tones, play around.
Getting back to exposure, use the histogram on the back of your camera, you can toggle it on or off with the navigation button, up and down I think.
Ideally a well exposed image will have data the full width of the histogram, without the white at the right climbing the wall. That means the whites are over exposed.
Use the exposure compensation button to adjust the exposure in aperture mode.
