I think an important concept is to understand the stationary state solutions. solving the time independent schrodinger equation will give us an infinite set of solutions. To get the general wave function we multiply each solution by the corresponding e^-iEt/h (each stationary state has its own allowed value for the energy); we use the Fourier's trick and equation 2.31 to get Cns. Finally we add all the solutions to get the general wave function. I think this is important because when we have the solutions for the time independent schrodinger function, getting everything else (expectation values for x and p and…) is straight forward.
