HI Carter, I think your questions might have a quicker response on the DaVinci Basics and Configuration forum.
You should upgrade to Resovle v9, its a no cost upgrade. To each of your questions specifically;
1) Resolve will natively decode and debayer and play RED r3d raw files. Just put them in the Media Pool. You can adjust decode settings in the Project settings, Camera Raw page in v9.
2) For a basic raw workflow, put the raw files in the media pool, set the RED resolution, quality, colorspace and colorscience for the project, or per clip in our new Camera Raw palette on the Color page, and grade. While technically correct there is 100% no need for LUTs if your output is REC 709 for TV. Just make the grade look good on your REC 709 monitor.
3) Dont worry about LUTs in this case. I'm sure you can make the grade look great with the RED decode settings and Resolves grading features.
4) Version 9 has 40+ pre made grades which you can find in the Gallery. Have a look at those.
I highly recommend you read the new v9 manual, from our web support pages or with the Mac download. It describes the RED workflow well.
