Two Situations in a Game Last Night

[umpire99]

This game was played under FED rules.

Situation 1:
Runner on second base. Batter hits the catcher's mitt for catcher's interference but the ball travels into left field and falls in front of F7 with R2 moving to third base. Should this have been called dead immediately or should I have let the play develop and give the offense the option of accepting the result of the play?

Situation 2:
Runner on first base. Wild pitch gets by F2 and ricochets away as he chases it down. The offensive coach is signaling for is runner to round second toward third as F4 fakes a catch and tag causing the R1 to slow down and stumble into second base. What should have been called on this play?
