Looks pretty good.
Keep the FC above 3. Do you have any CC?
Cal-hypo is fine, you can use it for chlorine for a while if you want. Every pound you use will raise CH by little less than 5. It will also raise FC by more than 6 so maybe half pound doses.
You're right no need to sweat the CH with a fiberglass pool until it gets above 300 - it it gets too high it can cause cloudiness.

How are you adding the cal-hypo?
