Have you guys heard of any chronic or common problems with this engine?
I just don't to throw money at possible solutions, I'd rather fix the specific one and nothing else.

Most likely its NOT the catalytic converter. Normaly plugged converters will cause a general loss of power and poor performance.
Replacing the plugs was a good idea, did the old ones look suspicious? Were there any signs of fouling or extreme wear? It would probably be a good idea to change the wires, cap and rotor also.
Common problems on this engine are most commonly excessive blow-by. This will force a fair quantity of oil into the air filter box and saturate the filter.
Another common Chrysler problem is the MAP sensor, these tend to fail regularly.
Chrysler products also rely very heavily on the O2 sensor, a sluggish or defective sensor will really affect the driveability of these vehicles.
Try the self diagnostics as mentioned previously, it may help to narrow it down.
When you do finally solve the problem I would highly recommend cleaning the throttle body and IAC passages. Pay particular attention to the butterfly and its mating surfaces in the throttle body bore. Then reset the adaptives, I usually do this with a scan tool but disconnecting the battery should do the job as well.
If all else fails a trip to your favorite repair shop for diagnostics may be a good idea.
Good luck.......
