Don't have the actual pathology report in front of me bu ounds like will be very important for you to follow up closely with your dermatologist. You should find out the exact mitotic rate. Mitotic rate is more predictive than Clark's level. If you have any mitosis you might want to consider a sentinel lymph node biopsy. If mitotic rate is 0 then you should be OK there.
Most important thing is to get regular skin checks which sounds like you are doing so you are taking care of yourself there which is really the most important.
