[Fukasawa] Need help with post titles and widget dividers on home page

Hi all. I just set up my wordpress site with a masonry layout but I’m struggling to change a couple of things.

1) I would like to remove the titles and text from the posts on the front page links while keeping the titles and text in the actual posts themselves. This way, my front page would only show featured images + the sidebar but when visitors click on each post link, they would see the title and/or text in the post webpages. Is this possible?

2) If you look at the sidebar, there are extraneous horizontal lines where my widgets would be. How can I remove these lines?

Any help would be appreciated!
