Building a rental site some help needed

I am new to Drupal I use it since November 7.

I am relatively new to PHP I have created some working code.

I have a multilingual site for renting a house.
how to ensure anonymous users can view my main component type (renting object) with all available fields. If I use http://localhost:8082 nothing is displayed. If I use the language data is displayed but only as a hyperlink. I want the content to show all the available text fields.

anonymous users must not be possible to edit the content

I have the following content type:
renting object with a lot of text items (this must be displayed in the language of the guest user). If I have more than one renting object the usage must be by URL like:
localhost:8082/villax
a week content type having price,data, occupied and reserved item. The contetn type holds 53 records per calendar year (all Saturday dates)
a booking content type with all the personal fields of the renter (name, address, birthdate, bank account etc). Maximum 6 renters where one is the main renter.

I think underwater the renting object (house), the begin and end week and the booking must be glued together. How to do this? Using hidden fields and usage of PHP?

How do I glue this to an application like this one http://members.chello.nl/jophof (safari/chrome and use the botton bar to book the house)

The site is multi lingual and I want to make it appear as a mobile web app for usage on the iPad. For this I want to use the query mobile module. Any advice on this is welcome.

The status so far is I have the component types defined. The language selector with country flags at the top. When I visit localhost:8082 no content is displayed.
