Customize Text and Text Location on Printique Product Page

I would like to be able to make changes to the text and the location of the text in my Printique product page for my photography business website.  There are at least two places where the menu allows me to add text onto my product page.  This is the page where my customer can select the type of print, i.e. canvas etc., and the size.  The problem is the text is too small and the location isn't ideal.  Also, I would like to add a URL to a page so I can explain the different print options in more detail to my potential customers.
