You WILL need larger injectors, and 42's wont cut it. The 42's are good to about 500whp, and you should be well past that on an LS1 at 15psi.

yes, for any FI setup you need a manifold referenced fuel pressure regulator and a return line. also you need a much bigger pump. give AZPS a call, they got some very nice fuel systems, and they do a lot of FI.
