VirtualHost

I'm trying to configure name-based virtual hosting, and I'm SO close, but I've got a question...

First off, here is the relevant info from httpd.conf

Code:
#
# Use name-based virtual hosting.
#
NameVirtualHost *:80
#
# NOTE: NameVirtualHost cannot be used without a port specifier
# (e.g. :80) if mod_ssl is being used, due to the nature of the
# SSL protocol.
#

#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for requests without a known
# server name.
#
#<VirtualHost *:80>
# ServerAdmin webmaster@dummy-host.example.com
# DocumentRoot /www/docs/dummy-host.example.com
# ServerName dummy-host.example.com
# ErrorLog logs/dummy-host.example.com-error_log
# CustomLog logs/dummy-host.example.com-access_log common
#</VirtualHost>

<VirtualHost *:80>
DocumentRoot /home/thatscri/public_html
ServerName thatscriptguy.com
<Directory "/home/thatscri/public_html">
allow from all
Options +Indexes
</Directory>
</VirtualHost>

<VirtualHost *:80>
DocumentRoot /home/thatscri/public_html
ServerName www.thatscriptguy.com
<Directory "/home/thatscri/public_html">
allow from all
Options +Indexes
</Directory>
</VirtualHost>

<VirtualHost *:80>
DocumentRoot "/home/billiards/public_html"
ServerName www.billiardstalk.com
<Directory "/home/billiards/public_html">
allow from all
Options +Indexes
</Directory>
</VirtualHost>

<VirtualHost *:80>
DocumentRoot "/home/billiards/public_html"
ServerName billiardstalk.com
<Directory "/home/billiards/public_html">
allow from all
Options +Indexes
</Directory>
</VirtualHost>

1. Does that look alright? Is there anything in there that should be changed up any?

2. The only way that I could get the websites to work with www and without www was to add two virtualhosts for each site. Is there a way around this?
