well if your page in indexed in google, then google has that page in its index... that page will then have a chance at ranking for a search term.
To find out if you site is indexed, go to google and type in site:domain-name.com into the search bar, then presto! Google shows all the pages of that site it has indexed. But watch out for when you see "supplemental result" next to a result, that means that page is in google's supplemental index where it will hardly ever rank for anything. "SEO hell - the Supplemental Index"
Well one of the things you could do is make sure that all your title and meta description tags are descriptive and unique to each page. That way google will see each page as unique and will likely index them all. If you'd like a site review, have a look at this forum: http://forums.digital-m.co.za/. The guys there will review your site if you make a couple of posts.
