Steep crushed grain in 4 gallons of water at 155°F for 30 minutes. Remove grains from the wort and rinse with 1 gallon of hot water.  Add the liquid and dried malt extract and bring to boil.  Add the hops, Irish moss (1 tsp @ 15 min remaining), and yeast nutrient (1 tsp @ 15 min remaining) as per the schedule.  Add the Sumatran coffee and the chocolate varieties at the end of the boil.  Add the wort to 4 gallons of cold water in a sanitized fermenter and top off with cold water up to 10 gallons.  Pitch the yeast and aerate the wort heavily.  Allow the beer to cool to 68°F.  Hold at the temperature until fermentation is complete. Transfer to a carboy, avoiding any splashing. Add the Kona coffee and condition for one week, then bottle or keg.  Carbonate and age for two weeks.
