Best Compressor 3.5 Settings For Blu Ray Authoring in Roxio Toast

I want to export a 2 hour FCP7 project for eventual burning onto blu ray (BD-R DL) disk using Roxio Toast and I was wondering what are the settings in Compressor 3.5 to be able to achieve the absolute best quality file to take into Roxio?

As an aside, is Compressor even required for this or can I import the full res FCP7.mov file?

Thanks in advance!
