I use hosgator for hosting. They have good support system. You can use nvu for website building as its free.
I think free software are not updated. So it will be better to use always registered original software.
I didnt get your question... but I think you are asking "How can this be?" There is no 100% wordpress? Yes, I don't use anything else to develop my domains. Nor do I use anything else to build my client's sites or charity sites. All wordpress 10,000%
lol I would have to add a couple of zeros to that figure. Wordpress is the most amazing thing ever created to develop domains. I can pretty much build any type of site imaginable using WP as a platform. Not to mention the SEO advantages and the ease of use for an end user who has no experience!
