You should be able to do the high idle mod that idles the truck up for PTO use. I did it on my F250 back in 06 when I got it. I don't know if the F550 was any different. It is just a matter of connecting a couple of wires to a switch. I used one of my upfitter switches. Unfortunately it was so long ago i cannot remember which wires are which, but the truck should already be wired for it.
A bigger alternator is a got change even without the pump. I have a 200 amp Quickstart large frame alternator. The older style large frame alternators will bolt on without any changes to the truck.
