1993 Ford Taurus - HVAC and Exhaust issues

Very low heat inside cabin, even with windows up and heat on high. While some heat does come into the car, it feels like it does it in waves. For a couple of mins it will feel mildly warm, and then it will get much colder for a couple of mins. I thought this was the cycling of the thermostat, but I've never felt it like this before. Even when the air coming in is "warm" it's still very cool compared to what it should be.
What I've done:
- Thermostat has been replaced less than a year ago.
- These tests were done from a cold start, and with the HVAC controls all turned to "Off" - I first checked the feed lines going into and from the heater core. After letting the car run for 5mins, the passenger-side line felt warmer than the driver's side line. After another 5mins, the drivers side was *very* warm, and the passenger's side didn't feel much warmer than the first time I checked. After another 5mins, the passenger side caught up with the driver's side, and they were both *very* warm and about the same temperature - the driver's side felt about the same temp as it did the second time I felt them.
- To see that the doors for the HVAC were working properly, I turned the car to Acc. and turned the HVAC knob all the way from hot to cold several times. I was able to hear the motor (on the HVAC door) working, and it sounded like foam was being seated when set to completely hot or cold.
White smoke from exhaust, and *lots* of moisture leaking from muffler and other parts of the exhaust. After letting the car idle in one place for a couple of minutes, there was already a puddle the size of a dinner-plate from whatever is leaking from the muffler.
Car at times also runs rough, and sometimes bogs down during acceleration (not sure if this is related).
What I've done:
After running the car for 5mins, I moved the car to another spot on the driveway, I looked over all leak spots, but it seems like anything coming from the car was from the exhaust.
I checked the engine coolant, and the reservoir is nearly empty. I could not see any other leaks on my driveway (note: this was only for a couple mins, so it doesn't mean there are no other leaks, I may have just not seen them) so this leads me to think one issue. I'm hoping not to say anything, to see if you guys come to the same conclusion as well.
Any input, advice, or things to look for would be GREATLY appreciated! Thank you all in advance!
