Google confusion

My search for google is below for a keyword

http://www.google.com/search?sourceid=navclient&ie=UTF-8&rls=GGLG,GGLG:2006-30,GGLG:en&q=elegant+michigan+wedding

Now my website was linked from

http://www.encorepartydjs.com


This is a PR2 and got me good ranking. Well now the link in google as you seen above is

http://www.encorepartydjs.com/index.htm


I have lost rankings in all four of my keywords for the main page. How do I make it so google uses the PR2 page for searches? Do I need to start using the/index in my link submissions? Is there certain code I need to contain so my site is indexed differently?

Your feedback is GREATLY appreciated!

All the links on your site point to the index.html version
Googl will think that if you are linking to index.html then that is the page you want everyone to see.

It doesn't matter which location is linked to internaly or externaly, As long as they are both the same.

So what do I need to tell my webmaster to change the internal linking structure? Also is this a good idea, should I do this soon?

Also, Goog considers wwwdotsite.com different from sitedotcom (without the www)

Yeah that's what i would do. It may take a while to come into effect, But once google realise that all links are pointing to one location it will focus all rank and serps on the same URL rather than diluting it.

and xeno is right, It's important to pick either the www or non www version of the domain and stick to it. Or even better still, Use a 301 redirect to send people (and bots) who view http://domain.com to http://www.domain.com

I am still confused, do I need to get rid of the index page? I want all my urls to be http://www.domain.com/

Keep the page there, But link to http://www.domain.com not http://www.domain.com/index.html
