If I don't wear the watch for sleep tracking, does this affect my VO2 Max, Training Load etc? Does the sleep tracking provide any data for any of the statistics that we can view?
Lack of sleep data won't affect those metrics directly, BUT not wearing the watch for sleep could skew resting HR assessment, and that might interfere with proper physiological metrics calculations.
It does calculate the heart rate you have while you sleep into average resting heart rate. I got my watch yesterday and during yesterday evening my average resting heart rate was around 68 but after sleeping the first night while wearing the watch my average resting heart rate had dropped to 59.
The device might give you a resting heart rate attained overnight while sleeping, but there's much debate over how to use this data. 'Traditionally' resting heart rate used for calculating heart rate reserve (HRR) is taken immediately after waking up in the morning. It is more than feasible that deriving a resting heart rate value during sleeping will result in a lower value. Does this really matter? Probably not in the scheme of things as the difference is likely to be only a few beats and will have little affect on HR zones derived from HRR using the Karvonen formula.

...and I guess the reason for that is that before we had these fancy devices it was a bit hard to measure your HR while you were actually sleeping, hence right after you wake up is the closest you get.
