I want to know is there a direct impact on the hosting plan. Why i am saying is, most linux hosting plan gives us modules for search engine optimization but not in windows plans. I have couple of site hosted with windows plan so how do I increase the search engine optimization for those without any external modules. I am planning to purchase dedicated IP for those too. Except from my code level optimizations (meta tags etc) is there anything else that I need to concentrate on hosting side or anything for ask my host provider for increase the search engine optimization specially for my windows plans.

The only real effects webhosting has on SEO are:
Both of these really only come into play if you are on a shared webhost who places too many website on to one server. The side effect of this is the server is slow and occasionally experiences downtime. Google has publicly acknowledged using pageloading time as part of their ranking algorithm although they have indicated that only very slow loading pages are affected by this. Additionally, only pages with an extended downtime will be affected as well.
What you may be referring to is Google's pagespeed Apache module. It is designed to "optimize web pages by applying web performance best practices".
One thing that JohnConde did not mention and I like to say is:
If you own an IP address which was for a spam site, then owning that site is kind of a risk. because crawlers have marked them as spam in their database.
I have not heard about any SEO module, don't believe everything you here.
