Hello stainless,

I'm afraid you won't get much response here. This is not a SEO forum, and while some SEO people do read it, discussions about Google PR and other SEO issues are off topic, and we won't be able to help you anyway.

If you check the forums listed in http://dmoz.org/Computers/Internet/Web_Design_and_Development/Promotion/Chats_and_Forums/ you will probably find places where you can get better help than we are able to offer
