How can I hide different options in the Marketpress control panel

I'm currently building a site using Marketpress and while I have much of the capabilities I need, I'm in a situation where I need a way to hid different options panels from my users.

For example I have a review plugin installed and I don't want any user below admin level to be able to change the review settings.

There are other standard options I also need hidden but overall I'm not sure how to go about doing that.

Any assistance is greatly appreciated.
