ok, it sounds like 2 different problems to me. I am a Ford Mechanic at a Ford Dealership and see my share of both problems. the smoke at startup (if blue) is most likely leaking valve seals, this is a common problem with these cars.

As far as pinging goes, that is spark knock, and most of the time its a dirty MAF sensor. you can try cleaning the hot wires with non chlorinated brake parts cleaner, but DO NOT touch the hot wires with anything. if this helps, you may want to replace the MAF sensor anyways, but most of the time I just go ahead and replace the MAF. you can try unplugging the MAF sensor, shutting the car off, restarting it, and driving it for a few minutes and then see if the pinging stops, if so replace the sensor.. if any questions feel free to email me.*
