Anytime brother, am just in process of learning myself & it's just beginning for me.
Regarding wax, you should ask your guy who detailed/coated your ride. For me, as I had surfed the net & also Ahmad Bhae who detailed my ride, both negated use of wax & it is working for me. I will share some clicks of my ride which are 1 month after being ceramic coated & maintained after giving her few washes along with spray sealant & quick spray detailers.
Well for starters you are doing good, rest it all depends upon the satisfaction of the results you want/get from the products. Moving up the ladder you can use CarPro, Nanoskin & Chemical guys products. To protect & maintain coat you are doing good. Just avoid dry dusting of your car & you should be good to go.
I would advice you to go for a Quick detailer as well. As a general rule of thumb, use quick spray detailor 4 times a month & sealant once a month in a after every wash. Rest you can adjust according to number of washes you give to your car. For me it is once a week.
Do surf following store, see products, get their review from YouTube & you will learn a lot.
