I exclusively shop only there for my LFS needs and Mike is super helpful and knowledgeable. Most of the corals in my tank and all my fish are from there (except my torches because I wanted a bit more exotic ones than they had at the time). If you have any issues, you can send them an email, call, or go back in and they might be able to do a water test for you on the spot. They also sell the other test kits you are missing.
I got plenty of Euphyillia from them and they are all doing amazing! And I added my frogspawn and hammer to my tank after about a month and had no issues so 'adding them too soon' might not be the reason (they also survived 2 tank moves) and like others suggested, testing the other params will provide more insight.
Also aussie torches are more finicky then their indo cousins.
Also, out of curiosity, what salt are you using to mix your water?
