Game help please?

I am working on a game where you have to eat the cheese balls and avoid these cheese monsters but i dont know how to make the cheese or the monsters move on there own in an unpredictable pattern.

The aim is to move you guy around the screen without getting hit by the monsters but eating as much cheese as you can. I was planning to make the cheese give + 10 points and the Monsters - 1 life.

I have got the guy moving with keys but i cant figure out how to make the cheese or the monsters move on there own. And i dont know how i would make them give points or deduct a life.

I realise i should have played around with flash a bit more And got to know more action script.

If anyopne could help me by posting the action script i should put in there i would be grateful or if they could send me and updated FLA file i would be even more grateful.
