If I want to make the max power of 350 (and I probably wont make it that high) what size injectors should I be looking at? 440 maybe?

I already figure a 190lph pump will suffice.
Stock rail is good enough

Go with a set of 550cc so your duty cycle will not be compromised. 550cc's are only like 10-20 bucks more. Not a big difference.

so um...peak/hold or saturated? I dont even get the difference

it doesnt matter but for ease of installation, I say get saturated to skip the installation of a resistor box. Also precission makes 580cc saturated. Their injectors are just as good, if not, better but cheaper.

The difference is just the impedance rating.
