Vdd is the conventional name for the power supply. The bubbles are the little circles on the diagrams (on the symbols for the PMOS in the inverter, the symbol for the inverter, and the symbol for the NAND)--they usually indicate an inversion.
Drain is marked by d, or D, source with S or s, Gate with G or g, and Bulk is marked by B, b or unmarked or completely omitted in the diagrams provided.
So (again on a very high level) , what is happening in a transistor is that when a certain voltage is applied to the gate, the source and the drain get connected electrically.
Are you asking for more specifics of transistor operation?
