Movement on uneven terrain

Hi all:

I've got a problem regarding moving my character on uneven terrain. I researched for a solution and found out the itween extension has such features. I already tried it, problem is it aint working correctly, everytime I click the character stutters up and down the y axis, but it still moves to the position where I clicked it at fast speeds. I temporarily crossed out itween in my list of solutions after that. I have a code here for my movement:

 void MoveTo() //function for moving
     {
         if(canMove)
         {
             Vector3 dir = targetPosition - transform.position;
             float dist = dir.magnitude;        
             float move = speed * Time.deltaTime;
             if(dist > move)
             {                
                 cc.Move(dir.normalized * move);                    
                 //Debug.Log(transform.position+" VS " + targetPosition);
             } 
             else
             {                
                 cc.Move(dir);    
                 anim.SetFloat(hash.moveSpeedFloat, 0f);  // sets the speed variable in the animator                
             }       
         //Rotation Smooth
         transform.rotation = Quaternion.Lerp(transform.rotation, targetRotation, Time.deltaTime * rotateSpeed);            
         }                
     }

The "cc" in the code is the name for my character controller. This script works fine with flat terrain (all animations works correctly, from locomotion to idle and vice versa) and also collides with other objects in scene. SO basically my goal is to make my character move through uneven terrain and stop (with corresponding animations also to stop) at a given point and also stop the animation where I clicked.

Any input would be helpful, Thanks in advance.

PS: Im using my own character model with bones and used unity's mecanim to animate the character with the rawcap motion asset.
