include comments in single post template call

I need to query posts to have them displayed on one page site:

[su_posts template="templates/single-post.php" id="4976" field="the_content"]

1) Any way to include posting and displaying comments with content?
2) Any way to include posts by category rather than single id?

Thank you much, keep going at this mighty plugin!
