You've got 2 fuel pumps on this model: main pump under the luggage tray near ECU (accessed from under the car) and low pressure in-tank pump. On my car the pumps are noisy only during start up, until they reach working pressure.
Mine 84 has been sitting idle for about 15 years in dry climate (AZ), so I had to replace half of the rubber tubing - fuel lines, brake lines, clutch line. You'll need new brake pads front and rear (don't bother with parking brake shoes). I didn't replace the brake discs but rather gave them a clean with medium grit sandpaper.
I would also remove the oil pan and clean it. Chances are that sludge has separated from oil and your oil pump is sitting in a bath of sludge. Gearbox and rear axle - I would change that oil as well.
