In addition, I have noticed there is not much difference between the upper and lower radiator hose temperatures (thinking t-stat may need replacing-directions on how to do so would be much appreciated). Any ideas as to what may have caused this or how to fix it. Was it a transient one time thing? Was it related to my other issues? Thanks for any input in advance!!

Highly unlikely that you've spun a bearing or dropped a rod unless there's something that you're not telling us.
Dual Mass Flywheel rattle from a misfire can sound pretty scary.
Tell us more about your car.
What year?
Mods?
Mileage?
Have you ever replaced the injectors?
Do you use the right coolant?
Interesting observation about temperature differences between upper and lower radiator hoses, must have been pretty darn difficult to reach the lower one.
What does the gauge tell you?
Thermostats aren't usual failure items, however a few who live in warmer climates have changed them out for extra cooling.
And people with modified motors gain some extra cooling by putting in lower temp thermostats.
Most with cooling issues find that their radiator responds well to cleaning out all the debris that our "bottom sucker" cars collect.
Bottom line is, need to know a lot more before we can make any really accurate arm chair diagnosis on your car.
