Fueling & Injection - What fuel pump?

I have purchased a walbro 255lph in tank for my 2000 camaro ls1. The more I read the more I tend to think I need to do more than just this pump. what should I get for a 10# s/charged ls1. It will have a mild cam 60# injectors, hoping for 550-600rwh. With the duel walbro is this a special setup or do you just buy 2. Do I need to upgraded for this hp.

A single intank Walbro should be able to handle that boost and power. I have the same injectors, same pump, same plans for the future.
