Sales page on a content site

Hi,
I'm new here, so please be gentle!
I run a blog on consulting and I also offer multiple information products and have Adsense ads on the site.

My site has a lot of traffic and a great sign-up rate for the newsletter, but the conversion rate on the information products could be better. I know some of this is because people can click away to other site content or to the Adsense ads. However, I also have good conversion on Adsense ads and my existing sales page for my major ebook is ranked well.

I'm looking at restructuring some of my content and generating new images for my ebooks (started experimenting with this yesterday). But I wondered if anyone else had struggled with managing multiple issues on a site. I can see that one solution would be to push all the other content and ads away from the info product sales page. Or perhaps I should just work on the sales page a bit more and aim at tweaking the content. I had found that keeping the page with the same format as the rest of the site helped with the trust factor (before I redesigned the site last year, I did not have any ads on the same page, but conversions actually went up when I put the ads on the same page, oddly enough).

Caveat: I am a marketing consultant, but this is my own baby and it doesn't get quite the same time, attention or emotional distance that projects for my clients get.

Thanks very much. This is a work in progress, so I welcome and appreciate all help. I imagine I'm not the first person with a popular content blog to run up against this issue, so if someone has asked this before, I apologize and welcome the links to those threads.
