Here's a rough image of what I'm trying to achieve. How do we lay out the center and right columns, as a single page?

Is this where we should be building a custom template? or using modules (not sure how to specify which quote, for example, to include on which page, though)? or a custom component? or is moslate the easiest way to approach (seems to have author usability issues, though)?
Here's an example of another series of pages we need to build (and preferably enable end-user editors to safely update):

Thanks in advance for your help!
