Re: What would you recommend I do now?
The block drains need to come out if you want ANY of the coolant in the block to come out. Pulling the lower hose will only get to the level of the attachment point of the water pump and hose. The amount of coolant left in the block below the water pump holes is substantial. About a gallon+ total for both sides.
If the leak is coming from the radiator and not the lower hose, then the radiator may be cracked. Like Joe 74 suggested, go get yourself a radiator pressure tester. That will show you any leaks in the system, whether it be a lower hose, heater hose attachment or backing plate on the water pump.
