help with custom field data

hello, hope someone here can help me.

i would like to do two things, and both require ‘getting’ information from a page / its custom field data, and inserting into another code.

first: in my category.php file, before calling up all posts from a specific category, i’d like to insert code that would call up the content from a page with the same name as the category name.

for example, for a category named ‘The Beatles’ i’d like to pull up the_content from a page also named ‘The Beatles’ and include it in the category

if i could get this to work, this second part won’t be as important, however i’d still like to know how to do it…

second, on a page i’d like to call up all posts from a specific category. the category id would be specified as a value from a custom field entry from that page.

i’ve used get_posts to pull up the posts, and get_post_meta to pull up the custom field data, however when i use them together like this, it gives me an error:

<?php
 $postslist = get_posts('numberposts=5&order=DESC&orderby=ID&category=<?php echo get_post_meta($post->ID, 'identity', true); ?>');
 foreach ($postslist as $post) :
    setup_postdata($post);
 ?>
 <div class="recent">
 <?php the_excerpt(); ?>
 <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
 </div>
 <?php endforeach; ?>

kind of new to more ‘complex’ use of this code so any help is greatly appreciated!
