Don't worry about testing the tap water for CYA as there will be none. No reason to waste the reagent. Don't test for it until a week after you have added it.
As your pool is filling, you may want to go ahead and drizzle in some bleach as each foot or two of water is added. Pour as far from the sides as you can reach, being careful not to splash you or the liner. Then, take a clean broom or oar or something and stir it around. When your pool is full, test the cl. Until you get some CYA (also called stabilizer or conditioner) in there, it will be hard to keep the chlorine from being lost to the sun. So, for the first week or so, you'll need to test at least morning and evening (and if you are home, can test in the afternoon as well) and each time add enough bleach to get the cl back up to about 5ppm. I think your volume is closer to a little over 17K gallons. I assume the pool walls are 52" tall? But, the water level will not be to the top of the wall, so you'll have more like a 4 ft depth. In a 17K gallon pool, each quart of 6% bleach will add just about 1ppm of chlorine. Use that as a reference to help you determine how much bleach to add each time you test.
Your Alk and CH are fine. (By the way, don't let a pool store talk you into adding calcium to your vinyl pool. NOT needed.) Your pH is fine at 7.2 but you don't want it any lower. If it drops any, you may want to bump it up with a little Borax.
You'll need to add some CYA. We typically suggest a level of around 40-50 for most pools. Let's have you start out by adding 5 lbs. slowly to the skimmer while the pump is running. Slowly so it doesn't clog pipes. That should take you to around 40ppm. Run your pump 24/7 for about 4 to 5 days to give it time to fully dissolve in the skimmer. Also, do not backwash or you'll just throw it out. (A new fill shouldn't need a backwash yet anyways.) About a week after adding it, test it. But, I wouldn't test it any sooner. No point to waste the reagents. Once your CYA is dissolved and in the water, you'll be able to go to testing and dosing with bleach in the evenings only.
The Taylor Technologies website has some online demos of testing that you might be interested in seeing. Here is the link:

(BTW -- I deleted your other post since you figured out how to run the tests.)
Do us a favor, please. To make it easier for us to help, if people will create a signature line with their pool specs, it keeps us from having to reread through posts to find out basic information. You can create a signature by clicking on 'settings' in the upper right-hand corner of the homepage. In your sig, please put type of pool, volume, type of filter, size of pump, whether or not you have a SWCG or any water features and the fact that you do or do not have a K-2006. Thanks!
Hope this helps. Come back if you have further questions and somebody will try and help.
