Autorotation with Tab Bar

[Soulstorm]

I have an application. The application consists of a tab bar controller, with a tab bar inside it, which has 5 tab bar buttons, each one corresponding in a navigation controller with a view controller inside it.

I have 2 questions:
1) Is it possible to have autosizing enabled only for 1 of these 5 view controllers?
2) When I enable autosizing in my views, the tab bar, and the navigation bars of the buttons get weird (no image, they get out of place, etc). What can I do to solve this problem? Changes in the autosizing preferences in IB do not seem to work.

This has gotten me very frustrated, as I am trying to enable autosize for one of the 5 view controllers but I don't know how to do it!
