All could be normal, depending on how much.
The 3208 Cat is famous for white smoke during warm-up, a later fuel injection system can reduce it. Running warm it should not smoke. Black or blue smoke is different, some black on acceleration is okay when warm, too much indicates restricted air filter, bad injectors, or injection pump out of calibration. blue smoke is noramlly crankcase oil burning.
Some vibration at idle is normal, enough to shake the mirrors is probably not. Different vibrations can mean different things.
Noise will be more than a gas engine, you're sitting on a 10.4liter V-8 diesel BUT, look in the engine compartment to see if the insulation is shot, it probably is. The noise can be reduced with new and better insulation, and new carpet, but again not as much as a new gas engine or a pusher.
The exhaust IMO should be routed out the left rear corner, but 4" pipe is not cheap.
Have the engine surveyed by a reputable CAT dealer, he can tell you much. Also look for maintenance records, a neglected Cat is an expensive one. Oil and filter changes, anti-freeze testing, valve-lash setting, and fuel maintenance is all important. You should also have good oil pressure, >35psi@idle.
These are all normal vehicle items. The difference is truck parts will last a long time, but are expensive to buy.
