Hi Chris, no problem, happy to take a look at what we can do with a little CSS.
You’ll need to add the code to your Site Header HTML so it applies to all blog posts:
<style>
.blog-post__author-section {
display:none;
}
Here’s a link to our knowledge base with how to add the code to the site header HTML
Unless you have a high subscriber count or plan to proactively encourage comments, I would turn off the comments to help shorten the page and focus more on your primary call to action for the post - just my opinion, but having an unused comment section doesn’t look so good, but since you’re using a facebook plugin maybe you have plans for this 
For the spacing between the header and the title, it looks like this is being caused by the size of your logo in the header which is pushing it further down the page than the template is designed for.
My suggestion would be to either reduce the overall size of your logo, or even remove the quote bubble from the top and keep your brand name so it takes up less space, or use the quote bubble as an icon only - you could even look at changing it on scroll if the theme allows so that it switches from a smaller version of your full logo to just the icon on scroll.
If you don’t want to change the logo, I can see if there’s some margin or padding we can squeeze in with CSS, but might have to get back with you tomorrow when I can take a closer look at the code.
