To the second problem, I managed to remove the featured image in the category page, but it still retains an empty column where the image used to be:

I removed the featured image by deleting this line of code in content.php:

<?php if ( has_post_thumbnail() ) : ?>
	<div class="entry-thumbnail">
		<a href="<?php the_permalink(); ?>"><?php the_post_thumbnail(); ?></a>
	</div>
	<?php endif; ?>
