You are right on track.

At the moment we are really in a holding pattern until the kit arrives
Make sure you have plenty of bleach or liquid chlorine on hand, you will use it up real quick at the beginning
You will need enough CYA (aka
cyanuric acid aka stabiliser) to get your pool to 30ppm, which by poolmath I calculate 59oz. This gets added by the sock method described in
Pool School - Recommended Pool Chemicals. I have assumed you have no CYA, but this would be confirmed by testing
I would also suggest a container of muriatic acid to lower ph. Both are available at a big box store
Check out poolmath at the top of the page and have a play around with it. This is how you figure out what your pool needs after you test
Put in the gallons of your pool at the top of the page. In the bottom yellow box select troublefreepool for your goal levels, bleach for chlorine and select your pool surface
Once you test you put those values in the left 'now' box. You can then change the right 'target' box to your desired goal, or leave it at TFP goals, click on calculate and on the right hand side it will say how much to add
As an example I put in 14700 gal pool, set my free chlorine to 8.25% (in the chlorine result box) FC (free chlorine) now of 3 - FC goal of 20 and it told me to add 370 ounces - dont actually add this to the pool, just see if you can get a match in poolmath for FC and CYA
