No he doesn’t need the springs as well nor does the rear of the car have struts. So no strut mounts to change, no springs to change only the shocks.
I agree with @oldtimer-11, replace with OEM, not Monroes. If thecar had the “soft ride” package, the replacement shocks are $155 each from Rockauto compared to $53 for a pair of Monroes.
