Default Fuel Pump Upgrade

Okay guys i need some help with what to do with upgrading a fuel pump in a 2007 NNBS 5.3. Im going with a mild turbo setup soon and would like to get the fuel system supported to do so first. I plan to go with a walbro 450 in tank but i need some help with what all is involved in making this happen with the stock fuel bucket. Im confused of what is the best way to go with the setup and need some advice and direction to whats the most common thing people do on turbo setups with return less style fuel systems.

if your truck is flex fuel the pump is golden to 550hp range... Maybe a little more.
