Elgg is very confusing. need help

I came to elgg from oxwall and this is my first question. Many of you may know oxwall. It is flexible and user-friendly. Elgg however provides more functionality with free plugins, but it is boring. I want a simple social network.

I am trying to do following things but do not know how:

  1. When user logs in, he should see a 3 column dashboard with an auto updating newsfeed where he can update status like in other social networks (SNWs)
  2. No friend feature, just follow feature. A user should see updates from the user he is following on his dashboard.
  3. No activity page and main menu.
  4. The user should not be allowed to customize the dashboard.
  5. Search area on top bar with autocomplete feature like fb, twitter etc etc

Can anyone help?
