new smoker have some questions

Just guessing here as I do not have your smoker.  But I dare say that the standard chips available at most stores will work just fine if they are of high quality. As for the probe, you need to set the cook temp for the element and the desired internal temp for the meat such as a butt or a brisket.  Don't bother on things like ribs and wings.  Your manual should  cover all this.
