Help with pages templates and iPhone/iPad

I am using the business card template to create a couple of versions of business card. Unfortunately, I'm finding the business card templates a bit confusing. Depending on which option I choose either modern elegant or basic there seem to be several choices and different types of choices under each of those I'm a bit confused Is there a help document or instruction booklet that explains the different template labels and exactly what they mean? When I look at the canvas for example it gives the size "texting is much too large for a business card. Even though I've chosen a business card option so I'm just a little bit confused any help would be appreciated.
