Too Many Queries

I am currently using this code to query specific posts by month and year in
a page template, so I have to repeat this query 12 times for every year
everytime the page is loaded:

<?php query_posts('cat=2&year=2006&monthnum=1');
if ($wp_query->post_count >= 1)
{
?>
<---do stuff-->
<?php
}
?>

I am worried that this is too many queries. Is there a better way of doing
this? Perhaps something along these lines:

<?php query_posts('cat=2&year=2006');
if ($wp_query->month_num = 1) && ($wp_query->post_count >= 1)
{
?>
<---do stuff-->
<?php
}
?>

I know month_num won’t work but is there any way of getting the month number so I can pass it in the PHP if statement? That way I only have to run one query for each year.

Thanks
