I use Salifert for almost everything these days (Ca, NO3, PO4, Mg, alkalinity). I only test NH3 and NO2 when a tank is cycling, and have been happy with cheap brands. Easy to read and reliable. I use a meter for pH. I liked Seachem's Ca test, the shirt from red to blue was very sharp, but the dry reagent tends to solidify. I also have seachem's NH3 kit, which is a pain but useful if you want to know free vs total ammonia.
As far as temperature, I aim for between 80 and 83 degrees in summer, 76-79 in winter. You certainly don't need to lower your temperature any more, and some "experts" would say you should raise it.
Regarding the snails, I would be shocked if the turbos were eating coralline. The only animals I have seen that can do that are urchins.
