For Sections, breadcrumb trail is automatically set based on the hierachy of sections and the page title is set to the last section in the trail. When you're working with modules, to add elements to the breadcrumb trail and set the page title you only need to do one thing: add a trail point to the Request object. Its probably best to only do this if the request is not an internal module request:

if (!$Request->isIncluded()) 
{
    $Request->addTrailPoint( array( 'url'=>$_SERVER['REQUEST_URI'], 'crumb'=>$Record->get_field( 'name' ) ) );
    include_once(SITE_TPL_PATH . '/header.tpl');       
}
