With both codes pointing at TP sensor, I'd certainly take the time to replace it, as well as make sure connections to it are clean, and good. Chances are, you won't be able to take part back anyway. As far as exhaust goes, if it's leaking in the right places in may cause improper readings at sensors downstream, but if not obvious leak, I wouldn't be concentrating in that area right now.

If it revs up and down you need retrain the car to idle. I know it sounds crazy but you need to ask dealer or local shop the steps to do it.

picREMOVAL - 4.7L
The Camshaft Position Sensor (CMP) on the 4.7L V–8 engine is bolted to the front/top of the right cylinder head (CMP Location—4.7L Engine).

It is easier to remove/install sensor from under vehicle.

Raise and support vehicle.
Disconnect electrical connector at CMP sensor (CMP Location—4.7L Engine).
Remove sensor mounting bolt (CMP Location—4.7L Engine).
Carefully twist sensor from cylinder head.
Check condition of sensor o-ring.
