The setup looks good except for engine management. You already have an OBD1 ecu, so why not chip it and run Hondata or Uberdata?

You shouldn't need a fuel pump for just 7 psi, but security never hurts. The 440's should be fine for anything less than 10psi.

Besides that, I recommend a full dyno tune after the install. I wouldn't worry about running rich as much as I would worry about running lean.
