That PO4 worries me a bit being so low as I'm afraid this will start damaging my SPS corals, so normally I would bump up my feeding, but with the dinos, I'm not sure what to do?

Based on recommendations of a few other reefers local to me (Arizona, USA) I was planning to start increasing my alk number closer to 10 or 11, but with the pellets keeping my nutrients that low, I will end up burning up my SPS corals. So, I can take the pellets offline and let the nutrients rise a bit, and bump up the alk number, but not sure what approach is best honestly to fight the dinos: higher alk, or lower nutrients?

I would suggest water changes then to bring down the nitrate level and leave the phosphate level alone. With low phosphate levels carbon dosing won't be affective anyways
