Of Course you should encourage your patient to monitor their HbA1c.
I like to get my patients in the habit of knowing their FBS too. As we do dietary and exercise interventions, need for meds (in NIDDM or Type II) may decrease rather quickly. I always make sure to report and document all serial changes.
Lastly, continuously stress the importance of daily exercise involving the lower body, especially brisk walking, cycling and running depending upon underlying fitness levels. Finally, the patients PCP is kept in he loop continuously to monitor, reduce or modify any medical regimes or other needs (foot and wound care, etc.)
