Very good questions!
As for what else can effect SERPs performance, I think the
competitiveness in a given market niche is a factor although how much
of a factor or even how it is determined, I don't know. How your site
is linked to is another factor, i.e. linked deeply or only to the
entrance page, link text simply being the site URL or descriptive etc.
As for IIS being a problem, the more likely cause of any problem
related to a given server or server platform is the knowledge and
ability of the one maintaining it. But from a search engine point of
view, a page is a page is a page.
