Looks like its time to bring the car to a mechanic/shop. These folks learn all about car diagnostic and carry most if not all the checks that you've described in this thread. Kind of a second nature to them mate... all it needs is a pressure test kit, which they 'all' have anyway.
Any reason you don't want to give the car to a mechanic? If you want to keep it that's what I'd recommend you to do
