Othe than having the fuel-pump at full-speed all the time, is there any reason or other modification I need to do in order to run a relay on the Supra TT fuel-pump with (4) 850cc injectors controlled by a PFC ?

Will the stock fuel-pulsation damper able to handle it ?

TIA,

Not needed and is known to shorten the life of the Nippondenso pump. I speak from experience. Replaced it with an Apexi BNR32 pump powered through stock wiring. Look into Chuck Westbrook's wiring modification to increase voltage through the stock system.
