If I am using a voltage regulator to bring a voltage down from 9 to 5
volts should I still put a capacitor before a TTL IC to smooth out the
current?

It's not really to 'smooth out the current' so much as to provide a low
impedance path for switching currents.

You don't really need one on *every* IC though. Just make sure each chip is near
to a decoupling cap.
