I think you are installing CSSU stable but expecting CSSU Testing features.

In CSSU Stable you have to install Oriention Lock Applet from the repo.
Forced rotation is in the CSSU Features Configuration App.
Also the Camera UI hasn't change in Stable yet.

If you have About Community SSU in Setting it's installed.

When you have CSSU Features Config installed and use the "Forced" option, I would read up on editing your usr/share/hildon-desktop/transitions.ini blacklist.
Things like camera-ui and image-viewer don't function well after being 'forced' to rotate.
