I recently heard that Moses when he died went to heaven and not to Paradise, also that he was resurrected. I might be mistaken by what I heard. Can you shed light on this for me if it is true?

I am not sure of the difference between heaven and paradise; in any event Moshe Rabanu was the greatest of all mankind and is rewarded appropriately. He is dead as the Torah explicitly says and will resurrect with all those that will deserve it in the days to come.
