Importing Posts For Specific Pages

Hey,

Basically what I’m looking for is to be able to have certain posts displayed on certain pages from certain categories.

for example:
Tutorials

I have a page called /tutorials/

I also have a post category called Tutorials and I would like all posts in the Parent & Child categories for Tutorials to be posted in the /tutorials/ page.

Once that is complete, I have another small question. Is it possible to exclude that category from showing up in the blog section of my site?

Here is what I have inside my page.php

<?php

$tutorials = "/tutorials/";
$currentpage = $_SERVER['REQUEST_URI'];

if($tutorials==$currentpage) {
query_posts('cat=22');
}

else {
the_content('<p class="serif">Read the rest of this page &raquo;</p>');
}

?>

Please help, thanks in advance.
