ActionScript2 for Random Falling Objects, etc

Working on creating a simple game with some disadvantaged kids and curious if someone could help with the following.

We have a game scenerio where the character goes across the screen trying reach a safe haven and in the process encounteres falling objects.

We need help with making 5 objects (all movie clips) appear randomly on the stage (from any direction) while the character is in transit. If the character is hit it must restart, if the character is hit 3 times the game is over. When the character reaches the safe haven, the game goes to level 2.

Can anyone help with simple tutorials in resolving these issues simply with AS2. We have looked around the web and found some hints but nothing that answers these questions in simplified ways.

Thanks in advance
