A feul pump is always good measure, but maybe not neccesary if you're staying with stock injectors and turbo.
As far as a FPR goes, if you don't have a way to meter and adjust fuel, (ie, wideband + piggyback or standalone) you can goof things up pretty easily. The factory ECU goes off of a know fuel pressure, and if you change it, adjusting for it may be out of the scope of the ECU's capability.

Also,
I would only change the fuel pump if you know that it's got issues. A stock Legacy Turbo pump outflows a stock WRX or STi pump. That's just how they did it back then...
