You might email Google and ask them why your ads are receiving no Impressions. I'm not sure on that.
As for telling how many Campaigns there are - I use . This will tell you how many searches/month there are for any given search term, as well as the number of results (web pages) and the number of ads on both Adwords and Overture. Its very easy to gage competition. Then, when you enter the keywords into your Adwords Campaign, it will show you the approximate ad placement based on your bid amount - you can play with this amount to get an idea of what the top advertisers are paying per click.
Hope that helps!
