How to Customize the Blog Template

I would like to customize the blog template in Woodmart. Specifically, I want to:

1. Remove the “admin” name from blog posts.
2. Disable comments entirely.

Could you guide me on where to adjust these settings? Are there specific theme options or templates I need to modify?
