Buddycraigg gives a great suggestion on checking the transmission seal area especially since it is in drive only and it was after the filter change.
The rough idle. Normally the sensors for rough idle can be your TPS, MAT and MAP sensors. You said you have checked for codes and there are none though.
My next step- when was your last tune up. Plugs, wires etc? Take a spray bottle of water and with the car at idle mist water over the plug wires all over and see if this changes the idle at all.
The clicking sounds like CV
Defective CV/universal joints may cause clicking noises or excessive driveline play that can be improperly diagnosed as drive axle problems. Clicking noise on cornering is possible a defective outer CV. I know you said the CVs are okay but they don't have to have a torn boot to be getting worn.
You can remove the tire and check the brake shields and other metal on the front near the rotors. But again, normally the clicking in a turn is the CV.
I would also if you have not performed a good tune up in some time do the tune up and also put in a can of BG44K fuel cleaner.
For your model vehicle, ever 30,000 miles you are supposed to change the plugs, air filter and PVC and inspect the plug wires.
