You shouldn't need to add anything except the snippet Paul gave you, namely:
Code:
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]
This assumes you have installed Drupal in your root ie. that it is available by going directly to your site
