I've always wondered how to change the template and the design of the page links.
I don't know what they're called but it's those arrows allowing people to view the latest page, next page, first page etc.

Also how to make the comments list and author notes a different color from the background template always questioned me.
Could someone help?

you'll have to learn how to code HTML. you can start by reading a tutorial. i've linked a basic one below. it should help you get started. once you've mastered that do a google search for a more complex one.
