Sounds like a reasonable plan, I will give my 2 cents worth on a few things.
1. Drain first, that will drop your CYA and TC readings once you refill. Go from there.
2. Use muriatic acid to drop pH. Alk will also drop, but measure pH while dropping with MA.
3. Test strips are so inaccurate, you would be better off with old reagents.
4. If you can put trichlor tabs in 3x/week, you can manage your pool with bleach 3 times a week.
