Are log book and other things like hours of driving negated in a solo/empty return run?

Nope.
I had to log my hours from the time I dropped off a rig at the dealer until I got back to my home base (running empty).

You could do some time off (unlogged days) and call it a vacation at or near point A but you still have to account for the time it takes you to movefrom the drop location (point A) to return to your home base (point B), or to the next pick up location (point B), otherwise your logbook will raise a red flag.
