WPThemeIndex integration with BuddyPress index.php?

My index.php from anIMass theme:
<?php get_header(); ?>


<div id="maincontent">

<article>

<div id="content" role="main">

 <?php

/**

 * The loop that displays posts.

 *

 * The loop displays the posts and the post content.  See

 * http://codex.wordpress.org/The_Loop to understand it and

 * http://codex.wordpress.org/Template_Tags to understand

 * the tags used in it.

 *

 * This can be overridden in child themes with loop.php or

 * loop-template.php, where 'template' is the loop context

 * requested by a template. For example, loop-index.php would

 * be used if it exists and we ask for the loop with:

 * <code>get_template_part( 'loop', 'index' );</code>

 *

 * @package WordPress

 * @subpackage anIMass

 * @since anIMass 7.0

	 *

	 * In Twenty Ten we use the same loop in multiple contexts.

	 * It is broken into three main parts: when we're displaying

	 * posts that are in the gallery category, when we're displaying

	 * posts in the asides category, and finally all other posts.

	 *

	 * Additionally, we sometimes check for whether we are on an

	 * archive page, a search page, etc., allowing for small differences

	 * in the loop on each template without actually duplicating

	 * the rest of the loop that is shared.

	 *

	 * Without further ado, the loop:
