Ok, after much extensive research and discussions behind the scenes here and other boards, this is what I found out and what I am going to use. This is based on the collective recommendation of many experts, not just pointless ramblings from novices like me.
What I am using:
1.) Castrol syntec 10W40 (On sale at Napa!! 10 quarts for under $60.)
2.) Napa gold(wix) # 7211 ($16.99) Overwhelmingly the choice of experts!!
3.) K&N air filter Part #: K33332773 ($31.38)
4.) New Oil Plug & crush ring #: W0133-1646532 ($5)
A lot of people swear by royal purple ($8.99/quart). It was too pricey for me. My two choices came down to Castro, and Mobil 1 High mileage
What I have learned:
1.) Oil Companies have limited the amount of vital additives in their oil, because of the epa.
2.) It all comes down to the film between metal parts rubbing against each other, what protects them and how long it holds up.
3.) Almost all experts laugh at Porsche's recommended Oil change intervals. 7500 miles max or at least once a year, less if you track or are hard.
4.) Stay away from 30 weight oils. 40 weight seems to be the ideal choice amoung the experts.
5.) Let your car run 15 to 20 seconds before you go, but don't let it warm up to operating temps. Experts say this will dramtically reduce engine wear. 90% of engine wear happens when you start the car. Some state it will add 100k miles to your engines life. And for gods sakes let your car warm up while driving before getting on it.
I hope this helps some out there that are like me and want to make sure you are using quality stuff.
Napa has Castro Syntec 10W40 on sales for about $5.5 a quart.
