Re: abs warning light on.
I think when the Haynes manual is mentioning that you need diagnostic equipment to bleed the brakes it would be to operate the ABS pump solenoids. This is being advised all of the time now because without operating them you may have some trapped air in the system.
However I can't see why you couldn't just bleed the brakes as normal and see if it makes things better.
If bleeding brakes by pumping the pedal it's a good idea to only ever push it half way down, never push it to the floor. The pedal never goes to the floor under normal use so there's a chance that the master cylinder will have corrosion in the unused area that can damage the seals if the pedal is pushed to the floor....just a precaution but worth taking in my opinion.
If possible use a pressure bleeder, they save all that pedal pushing carry on.
With regards to your ABS light being on...
The first thing to check is that all of the sensors are still in position and the wires to them aren't damaged.
