I would be investigating the fuel pressure and injector operation as they also cause misfiring. The vibration may be from the injectors not operating properly. ( leaking or squirting and not atomising )

It could also be your injector, try running a fuel injector cleaner to see if that helps the problem.

Poor performance, hesitation, sluggish and shaking

Those are cylinder misfire codes. PO300 is random misfires (meaning 1+ cylinders misfired) and the other 2 codes are for cylinder #1 and 2. Did you change the ignition coils yet on 1 and 2?

2004 dodge caravan 2.4 Hesitates during Acceleration and at idele

You should definitely replace the fuel filter though this probably won't fix your hesitation. It wouldn't hurt to replace the spark plugs this is usually the culprit on these engine. I have the same engine in a '99 caravan and found the for some reason the spark plugs on cylinder 3 and 4 loosen up after one year and cause a misfire between 45 and 50 mph under load (when mildly accelerating).
