Add product from my custom module code

[vinny.kb]

I need to add some products to cart from my custom module and i have used the following code

  $productToAdd = new Product(1, true, (int)($this->context->cookie->id_lang));

/* Select the cart */
              $cart = $this->context->cart;

/* Select the product */
               $product = new Product($idProduct, true, (int)($this->context->cookie->id_lang));
               $id_product_attribute = Product::getDefaultAttribute($idProduct);
               print_r($id_product_attribute);
               $cart->update();
/* Add to cart */
                $cart->updateQty(1, $idProduct, $id_product_attribute, 0);

and is working.

I want to do the following thing also

1. need to display a custom attribute like a prename  along with the product in view cart page

eg: if my product name is test i need to display it as MY test in show cart page. How can i do that with the above line of code. how can i add a custom attribute for that using code and display the same in show cart page along with each product.

2. while adding same product to cart it should be displayed as a separate product rather than updating quantity to 2.

eg : if iam adding product "A" to cart for the second time it should be displayed as two boxes of product data in view cart page.
