Wow. I'm sorry to hear this. What engine do you have?
The bottom end on Chrysler's LA engines is pretty robust; thrown rods don't normally happen unless you're racing, or ran your oil pan empty.
The heads are proving to be a problem. When Chrysler redesigned the LA heads in the early 90s to introduce the "Magnum" engines, it seemed like a good idea at the time, now, 20 years later, they are prone to develop cracks between the valves on the outboard cylinders. (Numbers 1 & 4.) I've had to weld and put hard seats in them. This may be your smoking problem.
From what little you've said, I don't think your rod problem, and your head problem are related, although this may not be the case if your engine was running very, very hot.
Keep us posted.
