Welcome!
While you anxiously await the pool, try out your test kit on your tap water. Don't waste reagents on the FAS-DPD test or the CYA test. What you're interested in is the pH/TA. That will tell you if your pool will need acid or borax to fix pH. It may need nothing. But post up your results, and we can advise you which stuff you'll want to have on hand.
You know you'll need bleach, so start comparison shopping and see who has what for how much.
You know you'll need stabilizer, since tap water will have none. So hunt for that, too. The HTH stuff at Walmart gets good marks, but really all you're after is 99% or better cyanuric acid at the lowest price, so check big box hardware stores, too.
You don't need the aquasmarte system.
It's pretty simple to get the pool going, since you have a good test kit.
Get the pump running and leak check. There's ten minutes. Measure pH and TA and add whatever to adjust as needed. Fumble around with the stabilizer granules and the sock. By the time that's done, pH should be close. Add bleach to get up to 3ish. Take the kids inside and get them changed and slathered with sunscreen. Go blow up the toys. By then, it's safe to get in. As the CYA dissolves, you'll need to raise the target level and add more bleach to keep it above minimum.
Once you're doing it, a lot of what you've read will start making sense.
