Need Help Creating my Tank AI Controller!

Hi I am working on a more or less simple AI Controller.

There is the Enemy with a "AIController" script attached and a "Point" prefab. (Empty GameObject, might make attach a partical so I can see it's destination during testing)

The "Point" prefab has a Point script attatched to it. All this script does is on Awake() Set the "end" public transform(as in end of destination) of the AIController script to the "Point" prefabs transform.position.

The part of the AI Controller I am working on now is a Wondering AI. The idea is the AI will have a (int)points(as in points in 3d space.) and (int)destination(Starting at 0) variable.

If the AI's destination is equal to 0, Instantiate a "Point" prefab making the variable destinations to 1.

If the AI's destination is = 1, the AI will smoothly translate to the "Point" prefabs position.

I have tried Transform.Translate, and Vector3.Lerp but I get weird erros with bolth. When I used the Vector3.Lerp, even tho the end.transform was that of the "Point" prefab, the enemy would go to (0,0,0). When I tried Transform.Translate I thought it would just snapto the position. but no.. the enemy very quickly moves along the X axis to like -4000.. and just keeps going and going...

So this is where I am stuck. How can I make It to where the AI will throw out a "Point". Get the position of that point(Already have that set on the PointScript) and then smoothly look at the point and move towards it.

Stopping when it gets within a certain distance would be great kinda like a "Within shooting distance". But im not worried about that I can probably figure that out on my own.

Here is the scripts I have so far:

 using UnityEngine;
 using System.Collections;
 
 
 /// <summary>
 /// AI controller. This script governs the behavior of the AI Enemy.
 /// If the AI does not have a destination, it will instantiate a "Point"
 /// into 3D space within the Random.Range parameters, and then move to that
 /// point.
 /// </summary>
 
 
 public class AIController : MonoBehaviour {
     
     //----------Variables Start----------
     
     
     
     public         Transform     end;                                //Our end position.
     
     public         Transform     start;                                //Our starting position.
     
     public         GameObject     points;                                //The "Point" prefab.
     
     public         float         waitTime;                            //The time to wait before finding a new 
                                                                 //destination. I haven't got to this yet.
     private     Transform     myTransform;                        
     
     public         bool         weCanMove             = false;        
     
     public         int         myDestinations         = 0;
     
     public         bool         thinkingWhereToMove = false;
     
     private     Vector3     pointPosition         = new Vector3(Random.Range(-1.0f,5.0f),0,Random.Range(-1.0f,5.0f));
     
     //----------Variables End------------
     
     
     
     
     
     // Use this for initialization
     void Start () 
     {
         //A Quick Reference of our transform.
         myTransform = transform;
     }
     
     // Update is called once per frame
     void Update () 
     {
         
         if(myDestinations <=0)
         {
             CreateADestination();
         }
         
         if(myDestinations == 1)
         {
             MoveToDestination();
         }
         
         //Creating our destination. I appologize for this part is poorly written.
         if(thinkingWhereToMove)
         {
             weCanMove = true;
             if(weCanMove)
             {
                 //Instantiate points at mytransform + the value of "position" variable, with our rotation.
                 Instantiate(points, myTransform.position+pointPosition , Quaternion.identity);
             }    
             
             //There is already a destination, prevent any extras being created.
             thinkingWhereToMove = false;
             weCanMove = false;
             
             //Here is where I would add a waitTime.
             //Now we need a new destination.
             myDestinations = 1;
         }
     }
     
     
     void CreateADestination()
     {
         thinkingWhereToMove = true;
     }
     
     void MoveToDestination()
     {
         //This is the translation towards the "Point" part.
         
         //transform.position = Vector3.Lerp(start.position, end.position,Time.deltaTime);
         transform.Translate(end.position);
     }
 }

Here is the PointScript:

 using UnityEngine;
 using System.Collections;
 
 
 /// <summary>
 /// Point script. This script only gets the AIController of it's target
 /// and set the target's "end.position" to the point's position.
 /// Allowing the AI to move towards it.
 /// 
 /// I know this is a bad way to go about this but since 
 /// for now there is only one enemy I am not worried about it.
 /// </summary>
 
 
 public class PointScript : MonoBehaviour {
     
     //----------Variables Start----------
     
     public     GameObject     target;                //The point's Target.
     private Transform     pointTransform;        //The point's Transform.
     
     //----------Variables End------------
     
     void Awake()
     {
         pointTransform = transform;
         target = GameObject.FindWithTag("Target");
         
         //Set the AIController's end.position to the point's position.
         AIController aiController = target.GetComponent<AIController>();
         aiController.end = pointTransform;
     }
 }
