I don't think the regulator will work for a couple of reasons. The first is that it isn't adjustable to what you will need. You will need 5-7psi and that one only goes to 4, so you could run out of fuel at wide open throttle. The other problem is that it isn't a bypass regulator. I could be wrong, but you have an EFI fuel pump that is capable of a lot higher pressures, so I think you may need a return style regulator. Maybe someone else could chime in here.
Mine has three connections. One from the pump (filter), one to the return line, and one to the carb.
The other stuff looks good. The one connector says GM TBI, so I hope that is the one that I used for the filter. The hardline one should work great. I would either get two of those hoses or a longer one that you can cut.
