Drupal 8.x

Greetings Everybody

I'm Shafa and very new to Drupal. I own a social network + news/reviews hub created on Dolphin platform. Lately Boonex has has released alpha version of their upcoming product Dolphin U. Before I make this migration I thought I look into other options on the market. I've read much about Drupal, specially with new version went into beta and I really liked it. I have some questions though that I was hoping some of the elite here can help me out a bit :)

Thanks very much for the great effort put into Drupal.

I am a bit frustrated by the lack of information concerning techniques of populating a bootstrap theme in drupal7.

Perhaps I am just being dense. In the old types of themes we have regions that had implied purpose. The use of the bands in a bootstrap theme have let me not knowing how to populate them.

In the past I would go to the system settings and choose a particular page to set as the front page. Place blocks in all of the side regions and then setup up views with main menu entries and certain nodes with main menu entries. This is intuitive.

Does anyone know how Drupal 8 field bundles works? They look similar to field groups. For example, can I create a field set bundle that consists of:

[Add item]

Is "looking up" information possible in Drupal 8 node fields? For example, I give a contributor the option to select their US State from a field list. On doing so, another field is set to the State abbreviation, and another field is set to the State capital.

eg. I select Alabama (shown in a select field), and then another field is set (dynamically, or on save) to the abbreviation, AL, and another field is set to the state capital, Montgomery.

I have an author content type, which includes a node title, plus fields for the named title (Mr, Mrs, Ms), first name(s) and last name.

On saving, will Drupal 8 let me combine these fields and put the result into the node title, or another field. eg.

Node Title (or field) = named title + first name + last name (separated with spaces)
