Warning: main(wp-comments.php): failed to open stream:

The old wp-comments.php has been “deprecated”, at least in general, so instead of:

<?php include(ABSPATH . 'wp-comments.php'); ?>

try using:

<?php comments_template(); ?>

in your index.php to include the comments template.

Nope, I don’t so chat. But if you need that sort of help, there are a number of WordPress gurus on IRC:
