If I understand you right, you want a link to a page that polls all posts of a specific category? That’s pretty easy to do:
Create a new template for your page. You can make a copy of index.php, save it as “page_homebrew.php” and add the template code at the very top of that page:
<?php
/*
Template Name: Homebrew Page
*/
?>
Modify the Loop of that page to only poll a certain category using query_posts. For example
<?php $page = (get_query_var('paged')) ? get_query_var('paged') : 1; query_posts("cat=X,Y&paged=$page"); while ( have_posts() ) : the_post() ?>
(where X and Y are the categories you want to include.
Write your page from the dashboard, choose your “Homebrew Page” as the template.
