Labyrinth Game Movement

Hi,
I am going to start a labyrinth style game.
However there are a few things I need help with.
What are there best movement methods so that the speed of the ball depends on the tilt of the phone?
How do I make barriers?
How do I make actors spawn In random locations in a certain area at set intervals?
Before you ask I am a novice
If there are any templates available I would only get them if they are free.
Thank You.
