Question about clean URLs

This is what I have been using to get my other 2 sites to work.
I really hope I can get this to work before we transfer the domain over...

# Apache/PHP/Drupal settings:

# Protect files and directories from prying eyes.
<FilesMatch "(\.(engine|inc|install|module|sh|.*sql|theme|tpl(\.php)?|xtmpl)|code-style\.pl|Entries.*|Repository|Root)$">
  Order deny,allow
  Deny from all
</FilesMatch>

# Set some options.
Options -Indexes
Options +FollowSymLinks

# Customized error messages.
ErrorDocument 404 /index.php

# Set the default handler.
DirectoryIndex index.php

# Override PHP settings. More in sites/default/settings.php
# but the following cannot be changed at runtime.

# Various rewrite rules.
<IfModule mod_rewrite.c>
  RewriteEngine on

  # If your site can be accessed both with and without the prefix www.
  # you can use one of the following settings to force user to use only one option:
  #
  # If you want the site to be accessed WITH the www. only, adapt and uncomment the following:
  # RewriteCond %{HTTP_HOST} !^www\.example\.com$ [NC]
  # RewriteRule .* http://www.example.com/ [L,R=301]
  #
  # If you want the site to be accessed only WITHOUT the www. , adapt and uncomment the following:
  # RewriteCond %{HTTP_HOST} !^example\.com$ [NC]
  # RewriteRule .* http://example.com/ [L,R=301]


  # Modify the RewriteBase if you are using Drupal in a subdirectory and
  # the rewrite rules are not working properly.
