Wordpress Page of Posts Problem

I have been having some trouble (i don't know any PHP) setting up wordpress to display posts from a specific category, based on what page is currently displayed (page.php below). I was pointed to this page (look at page of posts) for help but now I'm stuck. Can someone help me figure out the last details of this? Thanks a lot!
