ProRes FCP settings
 

After converting 5D2 files in Compressor @30fps what settings are people using in FCP Easy Setup?

You would need to create your own Easy Setup as there is not one for ProRes by default. However there is no real need as FCP will configure the Sequence Settings to match the first clip that you drop on the timeline. If the timeline doesn't match the clip there is a dialogue asking if you want to change the sequence settings (you probably saw this already). If you answer 'Yes' then you are set.

It's simple enough to create your own Easy Setup from the Audio/Video Settings menu. Once you apply an Easy Setup it 'sticks' even if you exit & restart FCP until you actively change the settings by applying a new Easy Setup or modifying it in some other way.
