After changing hoses and a radiator you have to make certain to get all the air bled out of the system, trapped air can prevent good flow. If you're positive air is out, you may want to check for combustion gases in the coolant - a sign you have a blown head gasket. Use a product like Block Tester to check for those gases. A blown head gasket overheats and over-pressurizes the cooling system, it could also explain the 'smoke,' if you have coolant dripping onto an exhaust header.
