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.

You could do thisusing the ' multi column/custom query' templete that is included with the theme. Look in the gold forum tutorials for directions

or you could try this plugin

Thanks for your reply Still haven't figured it out but I will and trying to do without a plugin. If I haven't by the time I need this element I'll make the site live and be back. thanks again.
