You don't need to drain any, just pull the hoses and it will automatically drain the perfect amount.

You can disconnect the hoses on either end, but I find it easier to flush the core with the hoses attached. Plus, most factory heater cores use plastic lines. If you break that, replacing the core isn't any fun. The plastic going into the intake will also be brittle, but is much easier to replace.

The air should bleed off by itself as long as the radiator is full. You could get a spill-free funnel, which goes on in place of the radiator cap and holds about 2 quarts of coolant. To assist the air bleeding, you can snap the throttle several times. That usually will get every bit of air out.
