To max out a GT2860, you're probably going to need forged connecting rods and low-compression pistons, a 6-speed transmission (the 5-speed gearboxes are a bit more fragile internally and will probably break at the 300HP you'll be making), and a clutch rated for maybe 275 ft/lbs. A ported NB-style head would also help.
In terms of engine management, no need for anything fancy in terms of fuel pump and FPR. I might not have gone quite so large as the 255 (some folks believe that they flow too much fuel for the stock FPR to effectively bypass at idle, though I can't speak to this personally.)
I'd start with a good ECU (such as a Megasquirt Plug-n-play) along with an Innovate LC-1 wideband sensor and maybe some 550-650cc injectors.

As for strengthening the transmission, it is called just buying a 6 speed for $600-$900. You can get Quiafe gears, but then you are getting to the costs of 3 or 4 6 speeds.

Then assuming you don't care about emissions performance, definitely go for the 1,000cc injectors. You'll never run out of flow with those.
As for the fuel rail and so on, I've never seen anything to suggest that a stock NA-style fuel system is inadequate for 300 HP. The NB fuel system gets into trouble at higher load conditions, but aside from using something like a Walbro 190LP fuel pump, I'd leave an NA fuel system well enough alone.
