Welcome to the 911 community.
A lot of fun is lying ahead of you.
A few hints, I'm sure I forgot some and I apologize if some of them sound like "kiddy talk" to 911 pros, I'm just trying to help:
1. oil temperature: after the oil temp gauge reads 90*C, you're free to go as hard as you want
2. the steering on the 997 Carrera S is "razor sharp", be careful when you're steering-in at high speeds in sharp twists and turns. A bit too much too fast...you get my point.
3. expect heavy and SUDDEN oversteer, especially when turning PSM off and/or turning chrono sport to the "sport" setting. Think again about point 2 when you try to stabilize the oversteer.
4. be careful in the rain and/or when the streets are wet. The traction seems to be fine but sudden oversteer or loosing grip instantly can be dangerous.
5. the rear engine is "pushing" from behind, always keep this in mind when driving fast, especially through twists and turns. This is a wonderful setup in experienced hands but it can be dangerous too, this is not the typical rear wheel drive car like the BMW M3, it is competely different. Caution!
6. DO NOT drive over boardwalks, etc. with your 19'' wheels. This is actually valid for ALL high speed tires, they can be damaged invisibly, resulting in a blown tire later on. Treat your tires with respect, they are the ONLY connection between the car and the street.
7. never play around with tire pressures, stay with Porsche recommended pressures, they are the MINIMUM pressures for safe driving. Porsche is very "anal" about tires and tire pressures, they really do a very thorough and extensive testing. Don't throw this away by listening to the wrong people. Track "hot shots" always recommend to lower the pressure but this is WRONG for street use. Also check the tire pressure as often as possible. Stay with Porsche recommended tires with the
N designation. DO NOT buy the same tire size/tire brand without the
N, you get a completely different tire.
8. always keep an eye on the oil level, especially over the first 5000 km. Stick with the Mobil 1 oil recommended by Porsche, it is a very good oil and works perfect. Don't experiment with other high performance oils, you don't gain anything extra.
9. use the highest fuel quality available in your area, don't use so called real "race fuel" because this usually lacks some important engine additives for cleaning, etc.
10. brake-in should be done properly, from my experience it is not recommended to brake-in a 911 in city traffic, you need higher rev figures. Try to stay below 4500-5000 rpm most of the time at the begining, avoid full throttle situations and treat the gearbox and clutch with respect too at the beginning. Also don't forget about the new tires, for the first aprox. 1000 km, they don't have their full grip "capability" and may feel different too.
11. be careful with automatic car wash installations, the rear of the 997 Carrera S is very wide, most installations have problems with it. If you're unlucky, you may scratch your rear wheels too, be careful.
12. the clutch feels different on the 911, you may stall the engine in the beginning. No real problem, you get used to it, just be careful not to rev over 2500 rpm when starting from standstill (unless you WANT a really fast start), it really isn't good for the clutch. Experienced 911 drivers manage to drive off from standstill at around 1000 rpm, it is fine if you manage to do it at 1500 rpm.
If somebody else has more hints...I may have forgotten some.
. Are there any good tips for the new 911 driver such as:
guess that says something about GT4 as a driving simulator. ( or my driving 
)
