Query Posts syntax

The code in the bought out theme isn’t using parameterized queries, and could be susceptible to SQL injection:

So to address that and answer your question, change:

if ( is_page() ) {
    $paged = get_query_var('paged') ? get_query_var('paged') : 1;
    query_posts( 'post_type=post&paged=' . $paged );
}

to

if ( is_page() ) {
    $paged = get_query_var('paged') ? get_query_var('paged') : 1;
    query_posts( array ( 'post_type' => 'post', 'category_name' => 'Collaborations', 'posts_per_page' => 5, 'paged' => $paged ) );
}

Big caveat, I wrote this in the forum text area (I haven’t tried running it), so I’ll make sure it’s valid when I get back in front of my work computer.

OK, looks like you need to use the category slug:

'category_name' => 'my-category-slug'

or category id:

'cat' => 22

Sorry about that…
