How do I get these things done in generatepress?

1- Need to improve the quality of pictures

 

2- After the sidebar ends, I need the posts to show in the homepage

This space here is free below. Is there a way to that the posts start showing up after the sidebar ends? on homepage and the category pages

 

3- In the post section, I want the whole title to show, and the image, text, and “Read more” are the 3 links to one page… I want to change it to 1.. with just Read more button and that’s it.

Having 3 links per post is bad for SEO… in my opinion. It should be just one clickable link.
