The best treatment should really be discussed with your doctor.
I suspect the answer would be:
Echo: do nothing. Treating valve regurgitation (i.e.: to rid of it) are mostly highly invasive and life threatening last resort interventions. Doctors will not do anything about 'trivial regurgitation'. In most valves this is a somewhat normal finding.
ECG: for the right bundle branch block (RBB)- do nothing. The echo would have shown if the RBB was significant. In the absence of echo abnormalities RBB is a begin abnormality to the heart rhythm. I actually have had it for 20 years due to Fallot's Tetralogy. RBB can indicates other more serious rhythm abnormalities. A cardiologist will assess the QRS interval in the RBB for its indication of a bigger problem(if I remember rightly this is greater than 160ms which is really long. I had open heart before that. )
The other ECG abnormality I know nothing about. The above was based on my experience with a Right Bundle Branch Block and leaking valves.
