directory index versus index.php problem

Hello!

Parts of my website were recently hacked so I decided to just start over from scratch since it was time to do something new anyways.

I’m having trouble remembering how to do a few things though, it seems.

I am at http://www.monkeyslunch.com
I have my blog installed in a seperate folder than my root.
It’s at monkeyslunch.com/blog/

I edited my htaccess to point to the blog/index.php page as the default page to load when someone visits the site.

However, when trying to access individual directories like
/blog/
where it would normally load the index.php file automatically its defaulting back to loading the directory information.

My htaccess file in my root folder looks like this:

RewriteEngine on
RewriteBase /

ReWriteRule ^index/?$ index.php [L]
DirectoryIndex blog/index.php

<Files 403.shtml>
order allow,deny
allow from all
</Files>

deny from 85.12.60.30
deny from 58.65.239.114

And if you’re not quite sure what I’m talking about, I’m talking about how these two links should load the same thing:
http://www.monkeyslunch.com/blog/
http://www.monkeyslunch.com/blog/index.php

As well I’d like any other directory on the server to load an index.php file if there is no index.html, .htm, .shtml, default.htm, etc page in the directory.
