No, you can store them directly and use standard accessors. Actually, this:
customer.getDefaultAddressCity()
is the same as:
customer.default_address.getCity()

(or, to be very precise):
hasattr(customer, 'default_address') and 
customer.default_address.getCity() or ''

And
customer.setDefaultAddressCity('xxx')
is roughly equivalent to:
if not hasattr(customer, 'default_address'):
   customer.newContent(id='default_address', portal_type='Address')
customer.default_address.setCity('xxx')

You can get many properties directly from a Person, like:
customer.getFirstName()
