PVCs doublet and triplets with exercise stress test

  Thank you very much for your answer to my earlier question.  I'm still just a bit confused, and would like a little clarification.  I want to be sure I ask the right questions when I go to the cardiologist in a few weeks.
  First, I have no objection to just living with the PVCs as long as they are benign.  I have read information that said only when they come in pairs or triplets or runs are they considered a problem.  The exercise stress test I had done years ago did show PVCs in pairs and some triplets, no runs longer than triplets.  That doctor advised me to medicate because of the pairs and triplets.  I did for a while, but quit on my own due to side effects with lowered bp, brachycardia, and increase in asthma.
  Are PVCs still considered benign even if they occur in pairs, triplets when provoked by exercise?  Stress test was done many years ago, doc or results no longer available.  Should this test be repeated, or is it fairly safe to assume that exercise will be no problem for me since I've had only mild symptoms.
  Is mild mitral and tricuspid regurgitation something that should be followed up long term by cardiologist?  Does this regurgitation mean MVprolapse or is there always some mild regurgitation even in normal valves?  The echo does not mention prolapse, only mild regurgitation in mitral and tricuspid valves and mild atrial enlargement.
  Finally, what does trace pulmonic insufficiency mean....is this normal or could it progress?  Could this be related to asthma?
  Thanks so much for your service to the community!
  If everything is OK...I'd much prefer to just live with the symptoms!
