We can tell from looking at your numbers that they are bogus. There is no testing that can give you reading to the nearest hundredth (two decimal positions). They do that to make it look so official but basically, it is meaningless for the most part. Then, they recommend that you add calcium to a vinyl pool. Why? Vinyl pools don't even need calcium.

Your pH and TA are fine. Leave them alone. Until you get your K2006 and can test yourself so we will really know what your numbers are, just try to maintain chlorine at about 15ppm. You can use the color chart at this link to help you estimate what 15ppm will look like on your tester since it will actually only read to 5ppm. http://pool9.net/oto-chart/
For reference, in your pool, each quart of 8.25% bleach will add about 3ppm of chlorine. Run the pump 24/7 and clean your filter as needed.

You do probably need more stabilizer but how much depends on what your reading is when you test it yourself. 4 oz. of stabilizer will only add about 5ppm of CYA to your pool. Assuming that your CYA is 29, which I doubt, then that would only put you at about 34 which is still too low. Wait to add any for now.

Once the kit arrives, test and post your numbers and someone here will help you decide what to do at that point.
