How can I display 3 comments on the main blog page?

Alright… I’m not entirely sure what you’re saying. I’m not currently using themes. I can provide code/file structure/screenshots if you need.

I originally half-built my webpage using HTML and CSS. Deciding that I wanted to integrate wordpress for a convenient CMS and comments system, I researched it, and changed my .html file to .php, and added the necessary code:

<?php
		/* Short and sweet */
		define('WP_USE_THEMES', false);

		?>
		<?php
		require('blog/wp-blog-header.php');
		?>

I then included the loop where I wanted new posts to display (with some minor edits, of course):

<?php query_posts('showposts=5'); ?>
				<?php if (have_posts()) : while (have_posts()) : the_post(); ?>

				<div class="post" id="post-<?php the_ID(); ?>">
					 <h3 class="storytitle"><a href="<?php the_permalink() ?>" rel="bookmark"><?php the_title(); ?></a></h3>
					<div class="meta"> <?php echo human_time_diff( get_the_time('U'), current_time('timestamp') ) . ' ago'; ?> <?php edit_post_link(__('Edit This')); ?></div>

					<div class="storycontent">
						<?php the_content(__('(more...)')); ?>
					</div>

					<div class="feedback">
				            <?php wp_link_pages(); ?>
				            <?php comments_popup_link(__('Be the first to comment!'), __('1 Comment'), __('% Comments')); ?>
					</div>

				</div>

				<?php
				$withcomments=1;
				comments_template('/blog/wp-includes/comment-template.php');
				?>

				<?php endwhile; else: ?>
				<p><?php _e('Sorry, no posts matched your criteria.'); ?></p>
				<?php endif; ?>

Then I added the $withcomments=1, to show the comments. Unfortunately, this makes it so it shows *all* of the comments, and I can’t find a way to make it just display the most recent 3 comments. This also makes it have a reply box, which I would like to only allow on the post’s page, along with displaying the rest of the comments as usual.

Is this enough info, or should I post my full code and file structure? I can’t post a link, since I’m running on a locally hosted server.

Ah, that helped! I’ve figured out how to display the last three, but I’ve got another minor problem: Replied comments aren’t in the correct spot. Is there a function or series of functions to detect replies and put them under their thread owners?

Also, just in case it’s needed, here’s the code I added to my main page in the loop:

<?php
				$args = array(
					'number' => '3',
					'post_id' => get_the_ID(),
				);
				$comments = get_comments($args);
				foreach($comments as $comment) :
					echo("<p class='commentAuthor'>".$comment->comment_author . '</p><p class="commentBody">' . $comment->comment_content."</p>");
				endforeach;
				?>
