Working on New Site

I am in the process of using wordpress to create a new site. http://www.askintuition.com I have to add the author credits for the initial vslider 2 that I am modifying. Had issues getting the credit to center. Using home page plugin and adsense delux serving linkshare code with simple message board forum and amazon store. WOuld love suggestions. Especially the ability to creat granular permissions in the blog. Would like to have specific blogs for each coaching call we do. The default roles in wordpress dont work for that. Subscriptions would be cool as well.
