Ok, so the fish store told you that some ammonia is safe, WRONG ! Even .001ppm ammonia can be deadly to fish and corals.
Ph is way low. 8.4 is optimal.
If you have zero nitrites, and nitrates, and your tank is 2 weeks old then in no way are you cycled.
That's wayyyy to many fish for a tank at 2 week's. Do tons of reading, ask lots of questions. To me it seems as if yet another lfs capitalized on a youngster with a hand ful of cash. I can't believe they sold you fish knowing you couldn't test your own water.
A test kit is hellaciously important, when your tank is this new you should be testing almost, if not daily.
