If you’re trying to get the forum list on the front page visible without anything else, just put something like:

<?php if( !isset( $_GET[ 'forumsonly' ] ) ) : ?> after <?php if ( $forums ) : ?> in front-page.php, then before <?php if ( bb_forums() ) : ?> put <?php endif; // forumsonly ?>.

That would allow you to put ?forumsonly in the URL to turn off the extra bits of the front page.

The other option would be to copy index.php into a new file and change the template it loads to something else and take out the parts you don’t want in there, but if bbPress changes anything in index.php in a new version, you’d miss out on the changes.
