adding addresses broken

Ecivicrm does not work for anonymous users:
1) In civicrm I have set only UK as a valid country, as a logged in user only the UK appears, as anon all countries appear
2) It specifies that only the first and last name are required in the billing address, yet you have to enter name in both the billing and shipping address (shouldn't nearly everything be mandatory on the billing address?)
3) It never stores any of the address data for anonymous users at all so you get an error in drupal:
