Answer 1: This should already work out-of-the-box. But if you installed 
MediaWiki a long time ago and were only upgrading it, you might be 
missing some mappings. To add them, you can manually execute the SQL 
query from /maintenance/interwiki.sql in MediaWiki core, or install the 
Interwiki extension to get a web interface to manage them. (The 
extension is bundled with recent MediaWiki tarballs.)

Answer 2: Just set $wgUseInstantCommons = true; in your 
<https://www.mediawiki.org/wiki/Manual:$wgUseInstantCommons>. The 
MediaWiki installer gives you an option to enable this, too.
