Replacing the 02 sensor or MAF sensor will only benefit your mileage if they are faulty; your first task should be to test these (per the FAQ's). If they are within spec then swapping them is a waste of money.

Better to check thoroughly for vacuum and intake leaks, and inspect your ignition system (plugs, wires, cap, rotor and distributor) and make sure your timing is set to spec. Also be sure your tires are inflated properly and wheel alignment is good.

It's easy to lose 3-5 mpg with a handful of little things not quite right; I'd look at those first before I started replacing expensive parts...
