Go to Appearance> Editor and select “single.php” from right and find this line and remove it:
<div class="comments_template"><?php comments_template('',true); ?></div>
Then do the same for page.php.
Then Select “stylesheet” from right and add this line to the very bottom:
.lay1 .block_comm, .lay2 .block_comm, .lay3 .block_comm{display:none!important;}
I dont understand your 2nd question.
