Qualifications for Deacons

Paul gave Timothy specific instructions to ordain elders and deacons as the leaders of the churches that they were planting.  The Deacons who we were first introduced in Acts 6 were to be dignified, honest, and faithful, not addicted to much wine, convinced of their faith and doctrine, mature in life and faith.  They are to be the husband of one wife managing their household well.  All that just so they can sweep the floor after a Sunday lunch.  What are all of the responsibilities of deacons?  Are they to be listened too or just the guys that take the offering every Sunday?  Are they to be respected in the office or is it just a stepping stone to eldership?
