Basic information on the CEO should prove easy to find. The company website, Hoover's and Google will all give plenty of good information about the CEO. Just make sure you're using a trustworthy website if you rely on Google!
Part 3 should be a little trickier. Take advantage of News and other article resources to find information about the CEO's leadership and it's impact on corporate strategy and culture. ABI/Inform, Factiva, and Business Source Complete should all work pretty well for this.
