Answer
The cam sensor is located above the crank pulley.  Since the code comes back, I'd say you should check it out.

The trans temperature sensor is in the lines to the cooler. Switches do fail, but verify your trans fluid temperature with a meter before dismissing that.

The other problems are just routine electrical gremlins from the sound of it.  IF you don't have a factory workshop manual and ETM, I suggest you buy them.
