Buy a 12 pound bag or so of plain old baking soda. This is the same as "alkalinity up" sold at the pool store for at least double what you can by it for at Costco/BJ's/Sam's. There will be NO CYA in the fill water; it is not naturally occuring. Buy the borax at the grocery store. Use that to increase the pH rather than "pH up" from the pool store. If you need "pH up", its the same thing as washing soda in the laundry section of the grocery store. Normally, it's recomended to use borax since it will not effect the TA like washing soda will. If you need to increase the TA as well as pH, you use the washing soda. Since you are starting from scratch, use the baking soda to set your TA, then set the pH with the borax/muriatic acid.
As far as adding the 50 ppm borates a detailed in pool school, I really wouldnt do that at all until you have a handle on everything else. It's optional, and until you have everything else woked out and are comfortable, it will just be an extra thing that you dont really need at this point, IMO.
