Some problems with localization

My website is: http://eshopbusiness.ru/

1. I can't add links to the feature bullets at the homepage.
2. How Can I translate BuddyPress menu tabs and MarketPress? BuddyPress localization already installed.
3. How can I edit box at the homepage (Get started in seconds for freeJoin Here!)? And Could I add there video?

Waiting for your replys!
