On new installation do you level out the bottom 4" of the sheetrock flat to
match with the rest of the surface for the new base molding?

Yes. Otherwise the base molding will not be vertical and coves and
miters will be a b***h to prepare and look weird. That's why some
installers prefer wallboard installed vertically. The choice may come
down to prevailing labor rates for drywallers. Many opine that
horizontal installation is cheaper and in some cases it might be.
Whatever, it would be interesting to have the views of finish carpenter
subs and drywaller subs on the matter. HTH
