These are not mutually exclusive. A reaction can be oxidation and exothermic. Oxidation reactions involve a change in oxidation state (charge) which is interpreted as a loss of electrons. Exothermic reactions release heat energy.
Not sure what L(s) is supposed to be, but regardless, the oxidation state of Na changes from 1+ in NaOH to zero in Na(s).

Yummy, Chemistry :) Redox reactions - Oxidation reaction This is a reaction in which atoms have undergone a change in their oxidation state.
Yes, because an element is in oxidation state ZERO. A reaction is redox only when there is a change in oxidation state of relevant species. So if a compound is formed from elements (as opposed to other compounds) there by definition has to be a change in oxidation state.
It has to be Pb(NO3)2 with NaCl as Pb has a +II oxidation state and NO3 has -I oxidation state. The reaction is the following: Pb(NO3)2 +2NaCl ----> PbCl2 + 2NaNO3
