if it does not go away over 60 and does not shake too bad at lower speeds sounds like your drive shaft is outta ballance if you do any off roading you may have bent it hitting an object or could be something like the diff joints worn or broken shaking it with your hand will tell you that (should not move)
and remember you got 4wd so you have Two drive shafts
Check for loose heat shields the cover the exhaust. I find this is the source of many rattles. They are made of sheet metal and if they are not clip or tightened down the low vibration frequency when the car is running at slow speed will cause them the hit the exhaust pipe/ front mainfold.
if the compressor is loose compression, normally it sounds noisy. then suction pressure is above normal and if you accelerate and maintains that high speed, let say 2000 rpm, the suction pressure goes down to the normal level and cools your air conditioning .
Well there is a rev limiter built into the pcm on your car. It is much lower rpm's in park and neutral. When u hit the rev limit of a particular gear selection, the pcm starts cutting out the injectors(fuel). This is normal. As far as the jerky feeling, the only thing I know of is a service bulletin that may apply to your car. It involves a revised torque converter for the transmission. It would only apply if your feeling this at speeds of approx 35 mph or higher when the torque converter lockup engages after a shift. Ask your dealer about a possible tsb for this if you think this may sound like your problem or search for tsb's(technical service bulletin's) yourself on the internet.
Could be carbon build-up on the pistons, causing erratic flame travel in the combustion chamber... 'pinging'...... Decarbon the engine and use a high grade fuel for a few tanks.... also an octane booster can help
