You can send a message to staff at Special:Contact and ask them to activate badges on the wiki of choice.

As to add custom stuff to the toolbar? Edit the MediaWiki:Wiki-navigation on your wiki as well. To add a favicon, upload it on the wiki via the theme designer. Can you elaborate what you mean about the blue box issue?
