Customizing the checkout page

I’m not clear on how to properly customize the Checkout page. This is the page that displays after clicking the “Buy Now” button in the Product Page.

It has elements I don’t want, for example a “Continue browsing” link and an option to Log in for faster checkout. I’d also like to change some of the formatting.

But I can’t find it. All I see under Shop is Thank you Page, Cart and Product Page – none of these are what I’m after.

Any clues?
