Once you get the good test kit things will get a lot simpler. We can tell exactly what's going on in your pool and if you need to shock you can test to make sure you're at shock level.
It doesn't surprise me that they didn't measure CYA, as Robbie said, it takes a while for it to show up, and some tests can only test it as low as about 30 ppm.
It also doesn't surprise me that the FC was zero. How long after you took the sample was it before it was tested? What kind of container was it in? was there any sun on the container during the time? Was there any sun on the pool after you added the bleach and tested last night? All that can consume FC.
I know it's frustrating but don't give up.
Go ahead and add the bleach and the baking soda.
