Default Ej20 swap in '08 impreza

So I have a '08 Subaru Impreza and I'm swapping the Ej20 into it. I already have the fuel pump, fuel lines, clutch kit, motor mounts, wiring harnesses, and the ECU. Would I have to swap my existing crossmember out for a 2005 wrx crossmember? Also, will my stock fuel rails be fine or will I have to completely replace the entire fuel system? Anything else I'm missing that is really important to make the swap successful?

I'm looking to swap the ej20 into mine as well but had no idea I needed to do any of that. Was told it was basically like a replacement. Take out, throw in.
