trouble enabling children of a networked player

 using UnityEngine;
 using System.Collections;
 
 public class NetworkManager : MonoBehaviour {
 
     public Camera standbyCamera;
     SpawnLocation[] SpawnLocations;
 
     void Start () {
         SpawnLocations = GameObject.FindObjectsOfType<SpawnLocation>();
         Connect ();
     
     }
     void Connect () {
         PhotonNetwork.ConnectUsingSettings("Version 0.0.1");
     
     }
     void OnGUI() {
         GUILayout.Label ( PhotonNetwork.connectionStateDetailed.ToString());
     }
 
     void OnJoinedLobby() {
         Debug.Log ("JoinedLobby");
         PhotonNetwork.JoinRandomRoom();
     }
 
     void OnPhotonRandomJoinFailed() {
         Debug.Log ("RandomJoinFailed");
         PhotonNetwork.CreateRoom( null );
     }
 
     void OnJoinedRoom() {
         Debug.Log ("JoinedRoom");
 
         InitialSpawnPlayer();
     }
 
     void InitialSpawnPlayer() {
         if(SpawnLocations == null){
             Debug.LogError ("No spawns available, Go fix it");
             return;
         }
 
         SpawnLocation mySpawnLocation = SpawnLocations[Random.Range(0, SpawnLocations.Length)];
         GameObject myPlayerGO = (GameObject)PhotonNetwork.Instantiate("PlayerMainA1", mySpawnLocation.transform.position , mySpawnLocation.transform.rotation, 0);
         standbyCamera.enabled = false;
 //multiple components need to be activated/enabled after the player joined
         ((myPlayerGO.FindChild("FPS_Player")).GetComponent("FPSPlayer")).enabled = true;
         ((MonoBehaviour)myPlayerGO.FPS_Player.GetComponent("Horizontal Bob")).enabled = true;
         ((MonoBehaviour)myPlayerGO.FPS_Player.GetComponent("Vertical Bob")).enabled = true;
         ((MonoBehaviour)myPlayerGO.FPS_Player.GetComponent("Ironsights")).enabled = true;
         ((MonoBehaviour)myPlayerGO.FPS_Player.GetComponent("FPSRigid Body Walker")).enabled = true;
         ((MonoBehaviour)myPlayerGO.FPS_Player.GetComponent("Drag Rigidbody")).enabled = true;
         ((MonoBehaviour)myPlayerGO.FPS_Camera.GetComponent("Smooth Mouse Look")).enabled = true;
         ((MonoBehaviour)myPlayerGO.FPS_Weapons.GetComponent("Player Weapons")).enabled = true;
         ((MonoBehaviour)myPlayerGO.FPS_Weapons.GetComponent("Gun Sway")).enabled = true;
         myPlayerGO.FPS_Camera.transform.FindChild("Main Camera").gameObject.SetActive(true);
     }
 }

What am I doing wrong when I am enabling the components at the end? I'm getting errors like "Assets/Scripts/NetworkManager.cs(48,92): error CS1061: Type UnityEngine.Component' does not contain a definition for enabled' and no extension method enabled' of type UnityEngine.Component' could be found (are you missing a using directive or an assembly reference?)" and "Assets/Scripts/NetworkManager.cs(57,28): error CS1061: Type UnityEngine.GameObject' does not contain a definition for FPS_Camera' and no extension method FPS_Camera' of type UnityEngine.GameObject' could be found (are you missing a using directive or an assembly reference?)"
