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.

Contact the owners of websites that reach an audience similar to yours, but aren't your direct competition, and ask if they will link to you.
Another way is to write really good articles / tutorials, and encourage others to link to them, or submit them to news syndication or news mashup websites.

No idea. Use Google Webmaster Tools. :)

Google Webmaster Tools is good.... also many people in Supplemental are using the same description for every page and in many cases the same title tags.... make sure each is unique... also do not have too much duplicated content on every page... except for navigation and footers etc
some time you may not have enough other content and the pages score high for duplication
