Plugin development

Hi,
I’m trying to develop a plugin with a top-level menu, and create meta boxes with WPAlchemy. My problems are pretty basic, but I can’t seem to find any resources for it.

This is the current code I have:
test.php

// Hook for adding admin menus
add_action('admin_menu', 'add_menu');

// action function for above hook
function add_menu() {
// Add a new top-level menu:
add_menu_page('Test Page Title','Test-Menu-Title','manage_options','test-slug', 'display_function');
}
function display_function() {
	include 'test-page.php';
}

test-page.php is then used to generate the menu page for the plugin. I’m stuck with 2 problems:
– How do I add WPAlchemy meta box on the menu page? It is added to the ‘Edit Post’ page by default.
– If I would like to place all the code in the same file, what other options or are there, or what would be the best practice?

I would appreciate any sort of help or links to references. Thanks.
