Creating Facebook Environment with Drupal

Question

I have installed Drupal 7 with Acquia Drupal.

I would like to re-create the Facebook environment especially:

i) user initiated mapping/creation of friend networks. ii) user wall for posting comments, pictures and have friends reply. iii) user profile creation.

From the little research I have done, I see that most of the modules available for Drupal Allow Facebook integration on a Drupal site (e.g. Like, post comment on walls from Drupal site...etc) and are NOT modules which allow the creation of a Facebookesq environment. I am hoping that I am wrong.

Questions

1) Can you please let me know which modules would allow the creation of a Facebookesq environment?

2) Slighty different topic - what is the most simple way to modify the underlying HTML/CSS files created by Drupal?

3) where is the "node" file stored?

I want to thank you in advance for your time and effort in responding to my questions.
