twentyten theme pages

Hi, I just downloaded the twentyten.

By default, all pages come with leave a reply comment area…
I wanted to eliminate that section.

I went to the page.php and from there, I ended up in loop-page.php

I then realized that these pages are not in use when serving the pages! I put various debug notes and they did not appear.

What theme or theme part is responsible for serving the pages in twentyten?

And also how do I change the mysite.com/page_id=6 url to mysite.com/page6

Thank you
