How can I query the db to access current post information?

Question

The correct way:

$my_query = new WP_Query('posts_per_page=2'); 

while ($my_query->have_posts()) : $my_query->the_post(); ?>

<?php

 global $post;
 print_r($post);  // <-- this is your postStuff

?>

<?php endwhile;?>

<?php wp_reset_query(); ?>

Normally, you dont’t need to globalize the post. There are helper functions that should be used instead to fetch information from the current post
