Why are you replacing all these parts, then worrying about the cost? Why was the car parked for two years? Did it develop a problem at that time? If so, that is all that needs to be repaired. I have a 1980 carburetor car with 45,000 miles, and a 1993 fuel-injected car with 4,950 miles. As you can see, I do not drive them very often. The gas in both of them is over five years old, but they run just fine. I do know people in some parts of the country have trouble with old gas becoming stale, but I have not run into that yet.
All the parts in the fuel supply system have gas in them all the time regardless if it is moving or not. Nothing happens to them from sitting. What you should be aware of is mold will grow in the gas if it has ethanol in it. If you have not replaced the parts already, replacing the filter would be a worthwhile, inexpensive investment after running a tank or two of fuel through it. At that point it would be good to expect the pickup screen inside the tank to become plugged. That should not be replaced until the mold is no longer in the tank.
I would not waste money on injectors. They do have extremely fine filter screens, but if your engine uses a fuel pressure regulator on the fuel rail on the engine, fuel flows through that regulator constantly, and back to the tank. The mold will not collect in those screens.
