Error with Different WP Directory

In http://www.briefme.com/ wordpress is installed in briefme.com/wordpress. I changed everything in the options, and index.php and blah blah blah. Everything works fine, except in two areas:

1) Attempting to reach the second page
2) Accessing a Page (that new feature in 1.5)

when I go into options and set my blog home to http://www.briefme.com/wordpress, everything is fine. However, /wordpress does not have a pagerank, and for our site based on search marketing, high pagerank is absolutely crucial.

I can even tweak the code on my own, if someone can even help me with where I should start from. Please help us as soon as possible.
