get product objects at checkout view (step.php)

In the checkout phase (the step.php file) I want to display certain text based on what products are in the cart.

What would be the best way to do this (to get the products from the cart). In other words, WHERE should I do this? Currently I am trying to get the products with $this->rows but it's kind of messy.
