What version of ACR are you using?
Are you using the Camera Raw plug-in on the way into PS or the Camera Raw Filter on a layer within PS?
The Camera Raw Filter layer filter (as opposed to the plug-in) in PS does not have Crop or Straighten because those are applied from within the PS interface, not within a filter. The Before/After split is what ACR has, now, in 8.x, not the Preview checkbox like before.
I don't have all tools available in Camera Raw ... I'm missing at least the straighten tool and the preview button. I updated my software today thinking that would solve the problem.
Neither do I, but then I'm on CS6.
