wordpress- affiliate sites

Hi friends,
I have been building sites with kompozer for affiliate click bank products.
Then I included wordpress as a blog like http://www.mysite.com/blog/
goal was: build an authority site.
Then create landing pages without nav bar etc.
Blog: to update with new articles which give seo benefit.

Now I want to know is it possible to use ONLY wordpress to promote clickbank and cpa offers.

These are the things I want to accomplish:
1. create an authority site for a niche like weight loss. This should have a feel like regular blog. eg. side bar with categories, pages, posts etc.
2. Then create few landing pages which doesn’t have a navigation bar. want to block search engines with robots.txt file.
Drive ppc traffic in addition to organic traffic.

Is it possible to achieve both goals.
