Congrats on the first Porsche! I recommend getting started with your oil analysis so you can establish a pattern. One sample might not be a entirely clear picture into the health of the motor based on the wear material unless its really bad. But overtime, you can get a much better idea for health and spot if something is not right.

As for the engine number, you'll need to check on the engine case itself to see that. With an 06, its unlikely to have a replaceable bearing via the service port but you can have your shop take a look when you bring you car to them next.

I'd recommend learning the oil checking nuances around the 997.1 since our oil metering can be fussy. The TL;DR though is only check prior to the first start of the day after the car has sat for at least 12 hours. Otherwise you'll have some inaccurate readings that might cause you chase your tail on oil consumption. Keep a log of how much oil you're adding as its quite normal for the m9x motors to burn some oil unless you're very lucky.

Anyways, good luck! Have fun and enjoy! I sure have as I have around 165k miles on my 06 4s and enjoy every minute of it.

Thanks for all the general and head unit suggestions! I don't think I'll be dropping the engine myself. I've never even changed the oil on a vehicle and I'm not recognized in my house for my handiness with tools and repairs, etc.
Engine# is on the drivers side of engine case and you and easily see it/photograph it --->Bend down behind the drivers side rear wheel - The # is stamped in a series of tiny DOTS on a flat rectangular case edge/surface and actually easier to read after taking a good focused photo using your flash on your iphone.
Sometimes depending on dirt buildup it can be difficult to make out the #'s but doable - This is my C4 Engine# M96/05 69600564 which is later 3.6L

I may do the same thing in the short term, pick up a transmitter. BTW, on the way home I noticed the FM station kept changing on its own from the one I had selected to some other station after a couple minutes. Is this a "feature" and if so can it be disabled? I generally wouldn't care that much, but whether I am to use a transmitter or just radio, it sounds like I will be going back to FM at least for a while, and I kind of want the station to stay put.
Strange, I hadn't experience that at all. I have an Aukey one that's been pretty reliable and quick connectivity.

Sorry - in case I wasn't clear, it's not the FM transmitter device that changes frequency (I don't have one yet). It's the actually vehicle radio / PCM that changes channels. However, thanks to @rickpriceuk I think I was able to fix this. I don't remember the name of the checked setting I changed, but I unchecked it last night. And this morning in my very first commute to work, the station stayed put. These older PCMs are funny little creatures...

Not the best photo, and maybe easier to read if I had tried to reach and wipe it off a bit first, but looks like engine number 68609452 to me. So, don't have to worry about the infamous "IMS issue." That's one less thing! ;-)

Good job! Told ya it's a PITA trying to read the #'s - I tried photoshopping your image. MAking it smaller and removing color helps.
Lil better---> Your complete# is M97/01 68609452 which is the later engine with better more robust IMS Bearing

Congrats on your new acquisition. I bought my first Porsche earlier this year (2006 4S) and I have loved driving the car, already added 7K miles in 7 months. A few recommendations...
I added the Mr12volt Bluetooth unit which has transformed the PCM - stream audio (radio, music, map directions) from phone and integrates phone calls (use PCM to make calls and included microphone for hands-free).
If you are interested in finding out more about your car, go to https://vinanalytics.com/ and you can get the original build sheet.
As recommended, make oil analysis part of the maintenance routine to build up a picture of changes over time.
Get a specialist geometry alignment to make sure your car is set up right. If you get it done at the right place, your car will feel more planted and tight when pushing it through those fast turns. I'm sure people can recommend specialists in your area - don't necessarily think that any indy can do it. They will also assess your suspension as part of the process, so you will get a list of potential costs for the future.
These are older cars and regardless of mileage stuff will perish/deteriorate over time. I went in thinking I would spend money on the car and there is a sick part of me that enjoys it
