Query posts

I’m wondering if it’s possible to, in my template, call a specific entry and then on the same page call a specific category?

For the main page of my site I’d like to have a welcome post and then after that show posts from the news category. I tried

<?php
// retrieve welcome entry
query_posts('p=3');
query_posts('cat=6');
?>

but that only shows the category and does some funky things to my layout. Any help is appreciated.
