Alk and hardness are a little high, but not a big deal. Alk should be in the 100's range, but if your pH stays stable, it'll be okay to stay on the high side. You can lower the alk using acid, but if your fill water is 250, then you're just going to raise it again once you top off, so you might find yourself fighting a losing battle. As long as you don't have metals in the pool, and do not chlorinate with cal-hypo, then you should be fine and can leave those two alone .

You don't want to chlorinate with cal-hypo though, because your calcium level is already high, and because the high calcium, combined with the high TA, will cause milky water if you add more calcium product. Your chlorine does need to come up a bit--you want to keep 1-3 ppm at all times, until you get stabilizer in the pool. On sunny days, that may mean adding more chlorine a couple of times a day so it never gets down to zero.

You can return the baking soda (or start cooking!) because it's used to raise alk, and yours doesn't need to come up any higher. Your pH is fine--Borax is used to raise it, but if you start using dichlor, you might actually need to to keep your pH up. Don't need it for now, but you might later. The muriatic acid you'l use if/when you decide to lower your TA, or if your pH creeps too high.

If you plan to use dichlor to chlorinate, then go easy on the CYA dose, because once you get it up to your target level, you'll need to switch purely to bleach. If you hit the CYA target just adding CYA alone, then you won't be able to use your dichlor without raising it too high. I wouldn't put more than about a 20 ppm dose of CYA in the pool, and just let the dichor do the rest.

Lookin' good so far!
