Multilanguage

Hi,
I’m in need of a multilanguage plugin for my site. I want a plugin where I can show different pages depending on witch language is selected. For example: in the English site there is page A, B and C but in the Swedish site only page A and C should be visible. Is that possible? Is there a plugin that can manage that?

I also need a plugin where I can control the user permissions. Is it possible to control it so that one user only can edit the content for one language? For example one user for the English content, one user for the Swedish content and one admin that can control all content?

Thank you!
