Hi, welcome to DaniWeb!
If most of your pages are in the supplemental index, then my first guess would be that a lot of your pages are incredibly similar and don't have much unique content ... either similar to each other or similar to other sites around the web (such as duplicate content). Are either of these the case?
The ONLY way to increase your page rank is by getting incoming links (preferably one-way) to your website from lots of different domains.
