A new engine is going to vibrate a little more than a used one. If the engine is a stock Zenoah it will vibrate, even when broken in, and tuned. If a smoother engine is desired a balanced one from Hanson, or Toxic Marine is in order.
For the rest of the helicopter minimizing vibration is the typical things like balance, and blade tracking.
For servos not working you need to determine if its the servo's, receiver, or something else.

When you said that sometimes the servo's don't work, my first thought was the ignition spark radiation getting into the receiver. I keep my engine wires as far from my servo, and receiver wires as I can. I also twist the servo wires, where possible.
