Newbie question : how to create a user-centric website ?

Hi drupal community !

I'm searching some advices.

I'm starting with Drupal, and I try to do a website where :
- admin create users logins and passwords (that's works pretty well natively with drupal)
- at user creation, a page is automaticly created (something like /user/mypage ).
- at user login, redirect to /user/mypage
- /user/mypage is a page for each user (not visible to other users)
- admin only can edit /user/mypage (integrate some stuff, like a poll, privmsg module, etc...)

I've tried some modules : login tobogan and login_destination. No one seem to do all the stuff I need.

Any tips and advices for newb ?

Thanks,
