You redirected me to this comment from my other one up the thread. But for #1, your blog post mentions that going with the USB cable option provides the best quality, which is what I use. Maybe a better wording is that VD is preferred for people who want to use it wirelessly.

For #2... that sounds like some kind of a software issue that only applies to DCS? Or maybe some obscure issue with the headset software? When I take off the headset in its normal link mode, it will usually pause whatever's going on PC-side, but I can just press the power button and keep it running if that's required. Never had an issue with this, let alone something that requires restarting the whole headset.
