Hi Razor,
You may use the following code to unload core css.

/**
 * Dequeue core css.
 */
function mpp_custom_dequeue_core_css() {
	wp_dequeue_style( 'mpp-core-css' );
	//wp_dequeue_style( 'mpp-extra-css' );// uncomment it to dequeue the grid framework.
}
add_action( 'mpp_enqueue_scripts', 'mpp_custom_dequeue_core_css', 11 );

The code you have posted for reordering is for legacy version of BuddyPress and it should be avoided after BuddyPress 2.6.0

Please see this post

For reordering the nav menu. In the place of component, you can use ‘mediapress’.

Hope that helps.
