For my assembly, I just built the V3 to stock spec, planning to make modifications after initial build. I am currently wondering about the same issues. Peter Florence has been emailing me with help and I asked him about some of those mods. I will report what he says.
I think that all of those changes are still a good idea. I plan to do them all. I just want to hear what Peter Florence thinks about them...
I changed Q2 to a ztx751, I think. I am not sure where I saw instructions for that change

Also, remember that R16 is no longer in line as it is printed on the board.
Oh, I should also note that the photo above is Peter Florence's photo, I just cropped it down.
