Don't run out and buy any O2 sensors until you know exactly what the problems are. The OBDII codes can often show the symptoms but not the cause. A lot of O2 codes can be caused by the MAF, vacuum leaks, etc. I was getting a bunch of CEL lights for O2 issues that were caused by the MAF going bad. A shop with a Durametric or PS2 system can confirm the status of the O2 sensors. Haven't had a CEL for two years, ever since I changed the MAF. Driving an 2000 S also, enjoy yours, there is no better feeling than the Porsche perma-grin.
