I was thinking LT4 injects and a pump whether it be aftermarket or LT4 high side I believe

If you simply add the blower with the stock car it will be in the 550-575whp running 7psi. With that setup your mpg will be just like the stock car when you are cruising on the hey. Obviously if you get into boost you are gonna watch mpg drop.
No. You do not need to upgrade the fuel to run in that power range. If you want to run more than 7-8psi, you will need fuel. I think I posted details when I was going through my setup and I outlined the exact timing for fuel additions.
