You will be able to find the correct parts as you go along. Since you don't know the internals of the engine, spark plug heat ranges are going to vary. Start off with a good tune up with the timing set at 17* initial and somewhere around 34* total. Drive it around with a combination of 30-35 MPH and highway speeds of 55-70 MPH.
