You are more than welcome, I am always glad to help where I can.
'index.html' is only one of many different default index names that Apache will look for. For a full list see the wiki article below;
One thing I did notice about your site files; you are using a mixture of upper and lower case characters in your filenames, be careful with this, as Linux (as used on the DreamHost webservers) is case sensitive, so a file called 'SomeFile.html' is considered to be a different file to 'somefile.html'
