If you're on a deadline, you might try Angry Ant's pathfinding system as opposed to rolling your own.

For the AI to make something follow you, you want to use something like this script I wrote:

function Update() { enemy.transform.LookAt(target); enemy.transform.position = Vector3.Lerp( enemy.position, target.position, Time.deltaTime * moveSpeed); }

Then you want to use the variables:

var target : Transform;
var enemy : Transform;
var moveSpeed : float = 5.0;

You can select the items as the target and the enemy (which chances are is the gameobject the script is attached to) in the unity Inspector view under the script options. The complete script should look something like this:

var target : Transform;
var enemy : Transform;
var moveSpeed : float = 5.0;

function Update() {
enemy.transform.LookAt(target);

enemy.transform.position = Vector3.Lerp( 
    enemy.position, target.position,
        Time.deltaTime * moveSpeed);

}

Also learn about Vector3s and Vector3.Lerp. You can read up about Vector3’s HERE and Vector3.Lerp HERE.
