Brushing once or twice a day until we get aggregate appearance, get rid of any white streaking, smooth out plaster. Once the pH goes above 7 start the pumps and filter?

I cannot help you on SOME issues but on others I can.

Alk or Total Alkalinity (TA). This only OK where it is, but it's not too high, it's TOO LOW! Yup, it's a buffer that keeps pH from bouncing around, and should be in the 80-125 range for your pool.

Calcium should be in the 200-400ppm range to keep it from dissolving the calcium out of your new plaster walls. You can add calcium for that.

As new plaster pools cure they push pH 'way up...so expect that.

As for the acid treatment and brushing of the new pool, I'm not grounded enough in that to help at all.
