BuddyPress.org

Hello I was wondering if some one could help me display if logged in show username and user avatar next to each other in header.

So far:

<?php
if ( is_user_logged_in() ) {
     global $current_user;
        get_currentuserinfo();    
        echo get_avatar( $current_user->ID, 64 );
} else {
    echo 'Welcome, visitor!';
}
?>

also would be cool if some one could point me in the the right direction for displaying avatar, users name, users bio and cover image so I can create a widget for logged in users too!

Would be awesome!

thanks in advance.
