After replacing front pads and rotors do you still need to bleed the brakes?

No, you generally do not need to bleed the brakes after replacing only the front pads and rotors. Bleeding is necessary when air gets into the brake lines, which doesn't typically happen during a simple pad and rotor replacement. You might need to *pump* the brake pedal a few times to ensure the calipers are properly engaging the new pads, but bleeding isn't required.
