I solved the first part with this code in bp-custom.php:

function bpfr_remove_nav_tabs() {

  $user = wp_get_current_user();
  $allowed_roles = array('subscriber');
  if( array_intersect($allowed_roles, $user->roles ) ) {
    bp_core_remove_nav_item( 'listings' );
    bp_core_remove_nav_item( 'invoices' );
  }
}
add_action( 'bp_setup_nav', 'bpfr_remove_nav_tabs', 15 );

Thanks a lot, hope you can help me with my second issue.
