First visually inspect the blockage by looking carefully down the barrel. Once you have diagnosed the problem, just grab the gun by the barrel and start banging the hell out of it on the table. Swearing loudly will help you channel your energy into this task more efficiently. That should do the trick!
Ok seriously, make sure you do everything you already said with the gun still pointed down range and your finger off the trigger, but that should be it to clear a stovepipe/FTE. As for misfires, I'm not sure if the XD allows a second strike (someone else will come along soon to clarify that), if not just do the same process as the FTE. When in doubt, put the gun down, still aimed down-range, and go get the range officer or other equivalent expert.
