Don't do this.
Blocking the EGR system is illegal (although not uncommon) and will make you fail emissions if your state/county requires it. The EGR system lowers emissions at cruise speeds and does not affect the performance of the engine. It closes when you increase throttle to ensure maximum power output of the engine when commanded.
The PCV system is far downstream of the air filter and MAF sensor. There is no way oil can get on your air filter or MAF sensor. The only improvement to the PCV system you can do is use an oil/water separator in the PCV valve vacuum line. This will catch most of the oil. It is not necessary as ALL PCV systems suck up fine vaporized oil in the crank case and deposits it along the intake system and most of those cars run just fine, mine included. Just change he PCV valve (less than $8 at the dealer) every 60k miles or when the valve doesn't open and close properly. My original PCV valve with 95k on it operated perfectly when I replaced it. Do NOT use generic PCV valves - they do not have the same flow properties as Motorcraft PCV valves!
I do not know the cost of the parts. I never had to do it before. You will have to pressurize the cylinders to prevent the valves from falling in and I hear it is a PITA job.
