548049 Install site to cpanel + add blog tab + olark chat

I have a completed website that needs installing onto cpanel [the hosting is all ready]. Once installed I also want; -A blog added to the website, so when you post new content its headings would be similar to websitedomainname/blog/blogtitle -Olark chat added. This is a simple line of code to add, I'm just not sure/have the time to do it. Google Olark for installation guide. Screen shot of website added.
