    NADH2 produces about 2.5ATP's compared to FADH2's 1.5ATP's (that's such a lie they tell you...what's actually going through the electron transport chain is QH2, but whatever...). This is because of the different amount of hydrogens the two compounds pump across the membrane. the more hydrogens, the more ATP's.

    Because NADH can function earlier in the electron transport chain than FADH2. The earlier the molecule starts in the chain, the more "electrons" it can transport and the more ATP can be produced.

    As a coenzyme in redox reactions, as a donor of ADP-ribose groups in ADP-ribosylation reactions, as a precursor of the second messenger molecule cyclic ADP-ribose, as well as acting as a substrate for bacterial DNA ligases and a group of enzymes called sirtuins that use NAD+ to remove acetyl groups from proteins.
