I read this yesterday and hoped some deacon would answer. The best I can do is give some ideas that I am aware of with my brother, who has been a deacon about 25 years. I would guess 3 years is necessary because there is a deep study of theology.
My brother was in the first group when the bishop decided to have deacons for his mostly 'rural' diocese. Being in his mid 30's and with 5 children (later 6), he was the youngest candidate. Yes, their schedule is full all the time. He usually preaches one Sunday a month in his parish, and did go to another parish every other month. At one time he was chaplin to the state prison, and is now director of the deaconate program. The wife is to be involved in her husband's ministery, and my sister-in-law works with the wives of candidates.
This is all extra to regular jobs, she teaches in the parochial school and he has a law office, helping disabled persons with applying for SSI.
He has presided at wedding vows for several members of our family, and did the entire wedding of his son. I believe he baptised his youngest daughter (now in college), and preached the homily at my mothers funeral.
Hope this gives some insight. Kotton
