You have multiple questions here. I can say any skilful mechanic can change out an AOS. You have to raise the car and work above and below the vehicle to remove and replace the AOS.
You can drive your Boxster if the AOS failure is minor, that is if the hole in the AOS diaphragm is small. I would guess many of us have driven our Boxsters for quite awhile with a failing AOS before the symptoms got worse, and then continued driving until we got the replacement part. The risk is if the hole gets bigger or the diaphragm tears while you are driving and there is a huge smoke screen behind you, shut down the motor ASAP.
