I can actually see more than 7 pages in the index… it looks like there are 81 pages overall. Here. I’m not sure if all of those pages are yours; if you own the entire domain and all the subdomains, I guess everything would belong to you.
In time, Google will find and index all of your pages. To speed up the process, or to get the spider to come around more often, obtain more inbound links — both to the home page, and to “deep” pages within the site.
I recently started using redirects on my site as well. I do this mainly so I can count the number of clicks on each link, not so much to cover the affiliate tags. Although if the search engines penalize pages for having visible aff tags, it might be good to hide the tags in some way. If you do use redirects, I recommend using a “301 permanent redirect.”
