Drupal 7.x

Hello,

I'm new to Drupal, but have a long web development experience.
I want to try Drupal to create my next site.

The basic idea of the site is (because i can not disclose the project itself, I'll describe the same project in other area, e.g. autos):

I need to create a catalog of:
Car Manufacturers -> Car Models -> "User Measured Car Value (UMCV further, these are values (some text fields) which user can add himself, based on his measurements of his car)"

I'm thinking af using CCK for very basic budgetting by setting up a field called "price" in CCK for a content type I call "shopping list".

Is it possible, somehow to make Drupal, based on the x amount of shopping list items, print a total in a block ?

I need to make my first website in Drupal, and I don't know if it's better to start with Drupal 6.x ou with 7.x.

Will Drupal 7 run on PHP 5.3 ?
