As for your undefined variables this is a php.ini error. Under the 'error_reporting' line modify it to say the following:
error_reporting =E_ALL & ~E_NOTICE
If you don't have access to the php.ini file in this case, you might be able to modify error_reporting at runtime.
Here's a look at ini_set() which will change ini values at runtime.

The .php3 error is coming up because your web server is not configured to have php parse .php3 extensions. You would need a .htaccess file which will work depending on your server os. After configuring one of those you'll be able to have php parse any extension you want. Check with your ISP technical support for OS requirements. They should be able to tell you exactly what you need.
