Multiple loops in Genesis

I think both issues can be solved by altering what’s happening inside the loop. The code you’ve posted are the arguments that are used for the query. There is a while loop which then goes through the results of the query and displays them. Try to find while ($wp_query->have_posts()): $wp_query->the_post();. Between this and endwhile; the results are displayed. There you’ll find echo get_the_author(). If you remove that, the author won’t be displayed. You can also alter the styling of the headers there.
