I don't see any point in adding more ammonia. the evidence is there that you already had some. (nitrites, nitrates) just wait till nitrites are 0 do a water change to reduce nitrates and u r done. this the beauty of cycling with live rock. just add your livestock slowly and it'll be fine. Of course there is nothing wrong with being extra careful and double checking by adding more ammonia. : )
nitrates will not reduce naturally in our aquariums they need to be exported out by water changes or biopellets....as far as your two part question. that is one of a few ways to maintain alk and calc, I use kalkwasser in my ATO. the first step would be figuring out how much is being consumed once you are all set up with corals until then I wouldn't worry about it. there should be no issue adding a fish at this point as long as ammonia and nitrites are 0.Along the same lines, a question regarding cycling. I am restarting a 37gallon cube with shallow sand bottom and about 1/3 of the original live rock I had in it as a FOWLR. I kept the one fish I originally had in the system (a 10 year old ocellaris clownfish). My goal is to convert this to an sps only tank. Tank has been up for 3 weeks after a 100% water change and nitrates consistently measure 10 using salifert kit. My questions are:
1. How long should it take for my nitrates to drop to an sps safe level?
2. Should I do a WC to lower the nitrates or just let it continue until it naturally reduces?
3. Anything else I should do to cycle it faster?
4. Any concern adding more fish at this stage?
5. Should I worry about dosing 2 part to maintain ALK and Ca at this point or wait until my nitrate is lower and then do a water change and start dosing?
Thanks for your advice.

also I'd like to add, it takes a few months for a tank to fully stabilize. I would hold off on spending a bunch of money on expensive SPS until you have a very good understanding of what it takes to maintain an SPS dominant tank.
Question then how did my nitrate go from 80 ppm to zero with no w/c in my cycle? I had about 30lbs of Dry rock ghost feeding in tote.
Here is day 3 of cycle.
