twentyten "POSTS" page template???

Hey wordpress community!

To sum this up, what ‘page template’ displays all of my “posts”?

For instance, in settings when I set my front page to display latest posts, what page template is this using?

Or does this add some bit of code to the 2010 default page template?

What I am trying to do is display latest posts on my front page, but I want to edit the page template where all of these posts are being displayed!!

I want to make it more of a home page rather than just a “blog”. But I haven’t been able to figure out which page template to add new code to.

If anyone could shed some light, you would definately help someone in need!
thanks in advance,
Nick.
