How to put all posts from one author on a separate page

I am very new(self taught - no training) to all of this and am building my site locally using ATA 3.7.7 and WP 3.3.2.
I am trying to create a page that will have all the posts from a specific author (guest blogger 1) appear on a separate page (Guest blogger 1 page) than the posts page. From what I have found from searching I can do that if I add to the file index.php the following:

<?php
if ( is_Guest blogger 1 page() ) {
query_posts( array ( 'category_name' =>Guest Blogger 1 'category-slug', 'posts_per_page' => -1 )
}
?>

Is this correct?
If so, is there a way to limit the number of posts on the page? (is that advisable?)
Where do I add it in the index.php file?
Will it just show the post excerpt? (That's all I want it to show)So you click on more to read the rest.
Is there a better way?

If this is not correct -- HELP!
Thank You.
