Faraaidh and Sunnats of ghusal

Q: A guy woke up for Fajr prayer. After the Salaah he went back to sleep. He then wakes up later with a "Wet Dream", it happens to be on Sunday, so he decides to take his bath after washing his clothes. Unfortunately he forgot about the Spiritual Bath and does only the normal usual bath. On Wednesday around 8am he remembers that he didn't perform the Spiritual bath but have been praying for the past 3 days and even led some people in prayers during this period. So now what is the ruling on such a person? Does he have to pay for all the prayers he performed during that period? And what about the prayers of the individuals he led, will Allah accept their prayers? What if he had intended to offer the spiritual bath but forgot. Can the bath becomes his ghusal for jannabah?
