How do I set the node title as breadcrumb?
You can use Menu Breadcrumb. It allows you to Append the page title to the breadcrumb (either as a clickable url or not) . Or you can edit your theme's page.tpl.php - simply add $title after the $breadcrumb variable.

There are also a ton of other breadcrumb modules if you want to get fancy:


Crumbs
Custom Breadcrumbs
