Hopefully the above post is a typo. You do have high pH so that is the only test you need to do. pH is a single value - there is no high and low (just different reagents to read different ranges) so your initial assumption was correct and your pH is 8.2. (FWIW this is what I expected with your location).
Have you read this link? It is probably your best bet as with the cycled media you have already added the process should go a lot quicker than the article suggests. That will allow you to add all of your proposed stock at once - after your ammonia and nitrites have stabilised at 0. The beneficial bacteria do need food (ammonia) to establish and thrive. As you have no fish now your water will show as "safe", but without enough of the necessary bacteria probably won't stay that way once you add fish. The method, as described, is designed to build up sufficient bacteria to allow you to fully stock your tank once the cycle is complete.
