BNW itself is a standalone expansion and as such it does not include all prior DLCs though this is not strictly accurate either.
BNW includes:
The New Gameplay Systems introduced in GnK like Religion, 100HP, Ranged Naval Combat...
Ethiopia (which was in GnK)
If you want a FULL Civ V experience,
Get Gold Edition upgrade for your Vanilla. Gold Edition includes all DLCs (which includes GnK) prior to BNW. Then, buy BNW.
