The presets on Adobe Media Encoder don't cut it, I've tried upping bit rates,
using max render quality/bit depth and it is an improvement but
has anyone figured out the magic formula for great looking youtube videos?
I don't care about file size but I do care about encoding time so will you see
a quality difference in a 35MB CBR vs a 35MB 2-pass VBR?
Should we just throw the highest quality file at youtube, and let it
do its thing, so Pro Res 422, HQ and or 4444?

You can do that. YouTube does accept ProRes formats. But the time you save from encoding to h.264 mp4 you'll lose in uploading time and YouTube Processing time with a straight ProRes file.

There is no such thing. Compression is as much art as science. For footage going to YouTube I encode at 1920x1080, 23.976 @ 50-100mbps CBR (depending on footage). Key frame distance is set to 12 (or whatever half the frame rate is). Maximum render quality.
VBR is good if you're trying to save space on your final file - say because you have a bandwidth limitation or a size constraint like on a DVD. VBR helps to maximize the bits by looking at the footage and estimating how much data needs to be thrown at a particular scene. If the algorithm determines it can get by with less data for a particular scene it uses a lower data rate for that area of footage. CBR means that regardless of the image being encoded it throws all the bits it can at it.
