1. The adjusting screw on the 2nd stage is too far out. Get a allen key(can't remember the correct size 5.5mm?) and turn it all the way in and then back off couple turns. Keep the adjusting screw all the way out during storage.
2. A slow leak is normal for a properly turned Apeks(with the adjusting screw all the way out). The leak should stop when you turn in the screw in no more than 2 turns.
3. Flip the lever to -ve before back roll-in and then reset it back to +ve. I would stuck one of my finger into the mouth piece to stop the free flow instead of knocking it on the side.
