What is the difference between 69436 and69421...if ventilating tubes are used then would it be coded as 69436?

That's correct. The 69421 myringotomy is (under general anes.) is making an incision and suctioning fluid out of the middle ear space - the 69436 is (under general anes.) is making the incision, suctioning out fluid if necessary and inserting a ventilating tube.
