A lot of questions for one thread.

  1. If you only need a limited amount of items, just create a class called Inventory that keeps track of them, something like:
public class Inventory
{
    static public int gasCans = 0;
    static public int bullets = 40;
}

  1. Use the new Unity UI. Learn more here.

  2. You can use the Unity UI for that too.
