Is the Mental Ray plugin enabled?
Settings/Preferences>Plug-in Manager>MayaToMR
Make sure it's loaded and set to auto-load.
That's the only thing I could imagine being the issue, since I bake AO all the time, and it prevents me if MR isn't loaded.
I've never baked Final Gather though, but it should be the same issue.
as joopson said, check that the mental ray plugin is loaded.then there is a (modeling)color->batch bake option. the occlusion is what you're probably looking for.
if you want to bake a final gather setup, you have to assign a suitable shader and bake color. then adjust you're render settings/scene as needed. it's bit complicated, but there are a lots of tutorials around..
