I am a total beginner and can't get my site to go live on the WWW!

Please help?
I have set up an FTP account with File Zilla and using Hostpapa for both the domain name and hosting. I am using Dreamweaver CS5.5 to design the website pages.
My problem is that I can see all of the files in the Hostpapa Cpanel home page but cannot manage to get them to go live on the Internet. My domain name is chesterplumber.org. Each time I type the name into Google it sends me to Hostpapa.
I have been trying to sort this problem out since before Christmas, I set up a support ticket with Hostpapa and was informed that my index file was saved using a capital 'I', The support staff assured me this was rectified by some amendment he kindly made, but my website is still not operating.
I would like to make a really useful suggestion to Hostpapa support team: Compile a step-by step live tutorial showing new users how to set up their account, transfer webfiles, use of ftp and most importantly how to upload the webpages on to the Internet from Hostpapa. I have followed the tutorials offered by Hostpapa but there are no explanations as to how the ftp links to hosting and how to use it together with hostpapa or Dreamweaver.
There are many website design tutorials available on You Tube but I haven't managed to find one that would show me how to upload files from Dreamweaver to Hostpapa and why I need a separate FTP account.
A short lifelike production offering sound and vision by a competent person teaching new users how to operate Hostpapa with a typical website building program such as Dreamweaver and a Ftp provider would greatly improve customers experience and probably prevent customer support staff reiterating the basics to many new comers.
