Welcome to the Q&A Forum

You could set it up in GWT but it sounds like you are using utm tags on internal links so you can see which physical links on a page are driving clicks.  If that's the case a cleaner solution is to upgrade your Google Analytics code for enhanced link attribution. I'm assuming you are using GA but if so this will allow you to see which links are driving which clicks and won't create tons of duplicate page titles in SEOmoz.

Let me know if you have questions,

If they were hit for sure then I would definitely have the links removed just to be safe.  You don't want to continue partnering with sites that are penalized until you know they have cleaned up their act.

I think you need your /author page to link to your personal google plus profile while the footer link should use the rel=publisher.  Your post pages should have author bio's at the bottom with a link to that authors' archive page.  Then your personal G+ profile should list your author page in the "Contributor" section.

You have the right idea with internal linking just don't over optimize the anchor text from your blog to your site.

As for content ideas your moving tips is a good start.  I would also focus on getting customer reviews to help your local seo.  Get either google places, trustpilot, or yelp reviews.

Other ideas could be moving nightmares to avoid, average cost of a move, moving scams, how to pack for a move, etc.  The more creative you get the better results you will have.  I highly recommend doing at least one info graphic per month.
