It should be simple I'm sure – Blog Template

After spending seemingly days looking for ‘thee’ answer Im somewhat pushed to submit my cry for help!

I would like to create a blog section on my website. Our site has been designed using WordPress by a third party and is fairly bespoke, to the uninitiated anyway!

Following the guidelines about creating a blog page gets me a little stuck as setting the Posts Page via ‘Settings > Reading’ doesnt really work as this is based on default template?!?.

Basically ‘all’ Im after is a page layout that holds the recent posts (say 5) in the main content area and posts navigation section on the right handside, something like a Categories list and List by Date (or something similar). Nothing too troublesome I thought. But its been a struggle.

To give an example, this is hte kind of thing I’m after :

Is there a plugin or a suggested page template that would help me out here?

Hope this makes sense.

Cheers
