Questions about the Pro version

Hi, I currently use the free version, and interested in upgrading the site's design, so I'm considering buying the pro version. Before I do so, a few questions (about the items I'm less comfortable with in the free version): 1. The 2 black thick lines (or boxes), above and underneath the site's title (where the social links are located, and then where the menu is)- will I be able to change it's color or completely eliminate it? 2. The site's title - centered instead of aligned to the left? 3. Homepage - will I be able to change the way the posts are featured? meaning the layout, size of pictures, etc. 4. Font - using different fonts for both titles, headlines and post text. Many thanks
