For the moment, I think you are OK. Your Tot Alk is high--We generally like to see it at 80-120, but in a vinyl pool anything up to 180 is FINE, and up to 200 is tolerable.
But get your CYA straight first. Since your water is clear, and your FC is fine, just get CYA to 30-50 and see how you are. If you get milky cloudiness, you'll have to lower Tot Alk, but if the water is clear, it shouldn't hurt.
You can read up on how to lower Tot Alk in the Alkalinity and calcium forum. Do NOT add more calcium NO MATTER WHAT THE POOL STORE SAYS! If your calcium goes high, with a high Tot Alk, you'll get milky water. Don't use Cal-Hypo to chlorinate either.
