It might be best to have someone rebuild the shifter, replacing all the worn parts; the labor cost would be cheaper than the third or fourth minimum S&H fee.

Stocking up would be prudent - Campagnolo discontinued the small parts for the earlier pointy-hood ergo levers, and eventually the thumb + front return + paddle springs fatigue and fail.
Re-taping your handle bar is the most difficult part of the rebuild and I wouldn't bother with sending or taking them some place.
