No on the shock powder. Your CYA is already way too high. From now on, only use bleach for shocking.
Those results scream ridiculosity. How could diluted water measure CYA at 50 and un-diluted at 150? Crazies. Not a single one of those tests included combined chlorine (total chlorine) results. For them to suggest you do or don't do anything to the pool based on no CC result is nuts.
Yet you are seeing algae. In such a case, you do not really need CC result, the algae is verification enough that you need to shock.
So, not only should you add bleach, you need to add enough to reach shock level and then keep it there till there is .5ppm or less CC, you have passed the overnight chlorine loss test, and the pool is clear. Don't be surprised if it gets cloudy during this process, this is normal and it's dead algae that will be filtered out over time as you shock (and after, it can take a while to clear everything).
Maybe I missed it, but you did order a kit right? Till that comes in, I would enter 0 in the now column, your target shock level in the target column, enter CYA of 150 in "now" and at the bottom it will show you minimum, target, and shock levels. Enter in all your other results in the now column as well. I'd use the un-diluted numbers from the store for the time being but as soon as your kit comes, post back with your own numbers and then we can help further.
Calculator will tell you that you need a LOT of bleach. Be aware that CYA that high makes shocking more difficult, if not expensive and if you miss shock level, you will miss killing all the algae effectively. It will increase the time it will take to finish the process.
No cupcakes for pool guy #1. If #2 isn't a dolt, maybe...
