Add blog to existing wordpress site

I have an existing wordpress website- pro seo [login to view URL] and i want this page http://www....../seo-blog to become a blog without affecting the rest of the site. I also want the bottom bar (website pages, recent work etc) to remain on the blog page and all blog post pages. I need the blog page to have a catergories section in the right sidebar (where contact form currently is) and each post needs to be listed in this sidebar. and every post must become an individual page. eg http://www......../seo-blog/seo-resources/ i also need an rss feed button on the page, along with facebook, twitter etc share buttons. these buttons should also be on the individual blog post pages.
