Is the amount show on my credit report on this site ALL the money I owe? If I pay that will I be 100% debt free?
I would not count on one site. Some lenders (creditors) report to one reporting agency, some to more than one, and some (primarily small) creditors do not report to any agencies.
Regardless, it is difficult to determine which lenders report to which agencies without reviewing your credit reports from all three agencies. You can get a free credit report from each credit reporting company at the link below.
