Hacked with redirect, help?

Ok. So, I’ve read through all of the awesome info. Thanks for that. And I’ve finally found the .htaccess file, but what should be in the .htaccess file? Do I need it to run? Here is what is in the file:
`
#0c45ef#
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_REFERER}

[hacked code removed – please don’t post that here – use a pastebin if need be – http://pastebin.com/ ]

</IfModule>

#/0c45ef#
# Use PHP5 Single php.ini as default
AddHandler application/x-httpd-php5s .php

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress
