I've done dozens of these, most of the time you don't have to bleed the ABS unit, but I've had 1 or 2 that fought me and I needed to.

Bleed brakes the best you can. I prefer a pressure bleeder. If the pedal still isn't great, you can bleed the ABS unit(you will need a bidirectional scan tool) and then you can bleed the brakes at the wheels again.
