Post Indexer Assistance

I have installed this plugin on the site. Here is the Wordpress/Buddypress site:
http://hardcorenerdity.com/

Now, you will see on the main page an area that pulls various types of posts like: Latest, Reviews, Most Recent Comments, etc. What I need to know how to do now is setting up a new section there that pulls the posts that Post Indexer grabs. What we would like is to be able to see posts made by other Buddypress members blogs.

How the current sections pulls the posts is with the code <?php query_posts
For example for Latest, the code is: <?php query_posts('cat=-648'.$theme_exclude_homepage_posts.'&posts_per_page='.$theme_tab_posts_num); while (have_posts()) : the_post(); ?>

In your instructions provided on the site, it is recommended to use a widget plugin called Recent Global Posts Feed as well, but we do not want a sidebar Widget. We want everything together within that area of the main page.

Any ideas? Thanks.
