Glad you like it!
As far as workflow goes, I think it just depends on what you're comfortable with. If you have more of a still photography background, then going from RAW2DNG (or similar) to Lightroom for processing, then into the editor of your choice, is one way to go.
Personally, the workflow I use and recommend, is to go from RAW2DNG/RAWMagic directly into Resolve, make your baseline/LUT corrections, then export clips and XML for editing. Obviously there's more to it than that, and it really depends on how well you know Resolve, but it's free, and it's the industry standard, so learning how to use it has definite benefits.
Oh, and if I'm reading your question correctly, the numbers you see are exposure "hints," telling you how far off from "correct" exposure the system thinks you are. You can turn off the "hints" in the ML menu system, if you don't want them.
Cheers!

My god, a wonderful and beautiful guide. I learned some new things! Cannot wait to see the workflow section. BTW do you what the numbers mean on the histogram? Like 0.6, -0.8, etc. I know it's for ETTR but I don't know what I'm supposed to do with those numbers. 
I'd love to hear your suggestion on proxies/XML/most optimal workflow.
