I would bet good money, that this is the condenser or coil from the symptoms OP has described.
I would buy new points at the same time as the condenser and coil, but not install them yet. OP's skill level is limited, so why add timing to the learning curve until it is needed.
BUT I would try blocking the hole in the carb first, if that is known to be a fix on this model bike.
Limit the repairs to one system at a time, until you find the cause. There is plenty of time to learn the rest of the systems.
