Yeah, I'd say you got some problems... might want to start by getting charging system tested, alternator and battery. A typical parasitic drain can't discharge a battery in mere hours, so you either got a motor running (fuel pump for instance) or a battery with a dead cell. Get those load tested. Thick white smoke is never a good sign, usually it means you're burning coolant, and can be a sign of a blown gasket. The "thump" under the floor can be caused by a worn torque converter lockup clutch, either catching or releasing when it shouldn't. If you're not a mechanic then maybe take this heap to one, or start planning on replacing the vehicle.
