I don’t really understand what all that above is at all. If you are trying to add a new nav item to the member and bp home themes then you need to do something similar to the following:

function oci_bpc_nav_item(){

?>

<li<?php if ( bp_is_page( OCI_CONTENTS_SLUG ) ) {?> class="selected"<?php } ?>>

<a href="<?php echo bp_core_get_root_domain() ?>/<?php echo OCI_CONTENTS_SLUG ?>

" title="<?php _e( 'Contents', 'bpcontents' ) ?>">

<?php _e( 'Contents', 'bpcontents' ) ?></a></li>

<?php

}

add_action('bp_nav_items', 'oci_bpc_nav_item');

That’s the way bpc hooks the action ‘bp_nav_items’ that header.php generates after displaying the default nav items. Your ‘Event’ and ‘Content’ items are displayed that way. You need to define a function that responds to ‘bp_nav_items’ and generate the appropriate html for the button.
