Moodle Editing Templates

How do I separate the blocks when editing a template? Example: <?php echo $ output->blocks('course_summary', 'cssCourse'); ?> I want to use the block with the course summary id, but he does not appear on the first page ... <BR> ................................................................ <BR><BR> Or else thought but can not develop further on is this: <?php echo $output->login_info(); ?> It prints the block login information, which gives to make loggof and edit profile, etc ... But I can about the other blocks, or disassemble the login info to separate for example Avatar User's his name ... etc... Still waiting for help ...
