Hi there TC7 and welcome to TFF!
kcharley and some of the other members have given some excellent advice up there, but unfortunately its sounding potentially like "too little, too late!"
The ease with which one can begin strolling down the wrong path and amazing! Many of us have kids who were very, very impatient to have fish. They are behaving like normal, healthy kids! For you, the important image to give you strength is to picture that the disappointment of watching their first new fishy pets die a slow death is much worse than the difficulties of getting through a month or two of explaining a "fishless tank!" The direction you are heading in your thinking so far is towards those deaths or at least some permanent damage to the fish that will shorten their lives.
"Fishless Cycling" is a powerful and important thing and a dramatic differerence for the fish. By stumbling on this web forum you have separated yourself from the vast majority of people who will never have a clue. Choosing to do fishless cycling would put you in an even smaller group who manage to learn the correct core aspects of the hobby in time to have their first fish be successful.
By getting a liquid-reagent based test kit you have made a second "best step" after finding this site, so there is hope! Your water parameters initially look really good for a fishless cycle too, which is good. Unfortunately, the LFS (Local Fish Shop) has thrown you a curve, providing you with a supply of "safe start," which, unlike a lot of the other good new equipment you have, is nothing more than a wish on the part of retailers that the startup of fish tanks wouldn't take so long that it ruins their chances of big sales and lots of people! Virtually all the the commercial attempts to speed up cycling are "snake oil."
The technical problem is that filters, which are the heart of the equipment end of the hobby, are really just pieces of hardware when you get them. They need to be "cycled" by a person with knowledge of the hobby. Its truly weird for newcomers. You need to grow two specific species of bacteria that will cling to the "biomedia" inside the filter. "Growing" this biofilter takes a minimum of about 3 weeks and a maximum of a couple of months and is unpredictable but essential.
Fish give off CO2 when they respire, just like mammals, but surpisingly, they also give off ammonia. The ammonia from this respiration, from fish waste, from excess food and from live plant debris are a deadly poison to the fish, burning their gills and causing death or permanent gill damage even in small amounts. The first species of bacteria (the ammonia oxidizing bacteria or A-Bacs for short) will eat this ammonia and produce nitrite(NO2) in the water.
The nitrite(NO2) which the A-Bacs produce is also a deadly poison because it latches on to the hemoglobin molecules of the fish blood and displaces oxygen, thus suffocating the fish and causing death or permanent nerve damage. The second species of bacteria we grow in the filter (the nitrite(NO2) oxidizing bacteria or N-Bacs for short) will eat the nitrite(NO2) and convert it to nitrate(NO3), which is much less harmful to fish, not great, but basically not something to worry about much and which can be removed via regular weekly water changes that occur when you clean the gravel with a siphon.
Once this "BioFilter" is successfully grown, the aquarist then has this amazing machine which operates with tremendous speed to remove these two deadly poisons constantly from the water and to render water that is clean, clear and wonderful for fish! The environmental cycle behind this process, the "Nitrogen Cycle" is fascinating and a wonderful topic for kids to learn about, no matter what age, so it can become a help on that end of things.
Since the 1980's there has been a "Fishless Cycling" process where pure household ammonia is introduced under a controlled procedure into the newly set up aquarium and water testing is used to follow the progress of the growth of the fledgling colonies of the two beneficial types of bacteria. As you can imagine, this process is just too "slow" for the retailers to successfully "sell" to beginners, so it drives them nuts! But for fishkeepers it represents a revolution. It consistently provides a near perfect environment for fish!

I just try to read them in the same light each time to be consistent. Which test kit did you get? Any fish yet?
