Changing Product Price Colour and Checking Cart

Hi,

Two basic questions:

1. How do you set a link so that visitors can check their cart?
2. How do I change the product price colour from red to another colour.

Thanks,

Thanks Nicloas,

In step 2 it says to modify the code:
span.hikashop_product_price {
color: #900;
white-space: nowrap;

I want to change the it to white so I replace it with:

span.hikashop_product_price{
color:#FFFFFF;
white-space:nowrap;

However on the product category page and checkout, it is still displayed as red.

Also when I check the page out put with Firebug, the colour code is still #990000???
