Screwy Play that acually happened

[varefump]

In a NFHS game, there was the following play:

Runner R1 on first and R2 on second, one out, count on the batter is 3 balls, one strike. Pitcher begins her pitch and base umpire immediately calls illegal pitch and signals delayed dead ball because the pitcher steps back with the non-pivot foot after the hands are brought together. Then runner R1 clearly leaves early before the release of the pitch. The base umpire immediately calls “Dead Ball, No Pitch, Runner at first left too soon!” The pitcher delivers the pitch and the batter attempts a bunt, but does not make contact with the ball.

What are the correct penalties for the two separate infractions, one by the defense and one by the offense?

I say that R1 is out (for violation of lookback rule) and R2 is awarded 3rd (for the illegal pitch). Does the dead ball negate the 'ball' being awarded to the batter?

Help!!!
