Yes, links to your homepage and your interior pages will help the authority of the other pages and, if they're optimized well, can help with their rankings as well. Good links to a page of a website does a positive effect on all other pages.

I am missing something here though--what is the purpose of your "core targeted page"?  "I'm wondering if 1-2 additional internal links from blog posts a month is really going to be enough?"

Enough for what?

I sent that exact ripoff report url to a long-time client earlier today when they asked me about Multiview.  I recommended that they not be a publisher for them.

Thought should then turn to the original decision made to hire that SEO firm and how a similar decision could be avoided in the future.

Call me batty, but in 10 years and a bunch-load of clients (usually agencies), I've only touched a small percentage of sites.  I write up the changes that need to be implemented so that designers/webmasters/programmers can either cut and paste what's necessary or have a good understanding of the changes that are necessary, and then I review once they're finished.  If they do have questions, I help them by phone.

Andrea,

You're OK using "postcard" in the child pages with child pages you mentioned, as those topics can be written about in ways that indicate distinct differences from the parent topic. However, in those pages, I'd limit the use of "direct" in your copy in order to distance them from the topic of the parent page.

or maybe this:

nopsts,

It's not going to hurt your site to have all those iframes but the content within the iframes will not help you in any way, either.  If you have plenty of good content on those pages in addition to what's in the the iframes, it's a positive for you.  However, you're out of luck if you are counting on the content in those frames to help you in any way.
