Want to make few changes but do not know how to do these changes

Hi,
I am redesigning my website and I am using Perth theme. I want to make following changes but I do not know how to make these changes.

  1. In portfolio single item page. Featured image is shown. I do not want this feature image to appear inside the single item page. Kindly visit this link: http://www.launchthewebsite.com/projects/netsil/

  2. I also do not want date and author name to appear under every portfolio item in single item page. I want date and author name to be removed from all portfolio item pages.

  3. Along with showing portfolio images on home page I want to show these portfolio items in same grid style on a separate portfolio page. So I could show more projects without showing many on homepage.

Kindly let me know how to make these changes.
Thank you.
