For the routing part, you can look at theses plugins:

• http://symfony2bundles.org/BeSimple/BeSimpleI18nRoutingBundle
• http://symfony2bundles.org/schmittjoh/JMSI18nRoutingBundle

If you want to change your locale (do it very early with a kernel listener for example) :

$container->get('session')->setLocale('en');
