Does it require any special Porsche tools for the various fittings?No special Porsche tools. Porsche's A/C system is just like any other modern A/C system running 134A refrigerant, where the high and low pressure ports are common for all manufacturers.
Are there any other consequences to consider for this service?If the service is done correctly there should be no consequences.
But, having said that, the A/C system in a car is a sealed, closed loop.
If it is low on refrigerant there is a leak which needs to be addressed.
The procedure that Marc describes above is the correct one.
Generally the leaks are corrected by evacuating the system, replacing the leaky part and recharging.
But if the leak is small enough in a part that's costly to replace, many people opt to recharge periodically (once per year or such).
Keep in mind that when there is a leak in an A/C system, compressor oil escapes so just recharging refrigerant in the long run can cause damage to the compressor if it has lost enough oil which isn't replenished.
