Pages to display posts with certain categories

This is the website in question: LWF

Basically what I want to achieve is that the pages Events, Media and Blog will display posts that are assigned the related category. So, for example, if you publish a post with the category “Events” it will sit on the Events page and nowhere else.

I’ve achieved this to a certain extent using the method outlined on this page:
https://www.tammyhartdesigns.com which involves making new template pages.

However this simply lists the posts and does not render the title a link-through to a single post or allow commenting both of which I need.

I can’t tell you how much I’d appreciate some help here, I’m close to nervous breakdown and may murder someone to death.
