I would think I just needed a 2 wheel alignment for the wife's front wheel drive car but then somewhere I've read stated its better to have a 4 wheel alignment done. Now I'm confused so a little advice will be appreciated.
Some cars are adjustable in the rear end to ensure that the rear tyres follow in the tracks of the front when driving in a straight line. Otherwise your can may crab, that is, the rear wheels are slightly off to one side. It can affect cornering a bit too.

Yes, you should always align all 4 wheels whenever possible. (Some cars have no or minimal adjustment in some locations.)
