I just ordered my Tesla a few days ago after a 24 hour test drive in an 85D, so I'll give my thoughts on the options and why I chose what I did.
85D vs. P85D - I have honestly never driven the P85D, but the 85D is FAST. I gave quite a few test drives over those 24 hours and not a single person wasn't blown away and still talking to me about it. There was a lot of screaming and laughing going on. The force of the acceleration can make you a little sick and even briefly affected my vision a couple of times. I have no doubt the P85D is impressive, but I've been told that the difference is not that noticeable and 1.3 seconds just was not enough to justify $20k for me. The 85D is already dangerously fast - likely faster than any car you've been in. Even with the 85D, you can look around almost anywhere you are (at least in my area), and be pretty sure you're driving the best-performing vehicle around.
Dual vs. single - Dual is faster with better range. But, the real reason I went with it was that I'm living in Ohio and want it for the weather. I'm not so sure what I would have done in CA, but probably still went with dual due to the first two points.
Pano roof - Definitely went with it. I've heard that the heat transfer is minimal, and that was my experience over a very hot and sunny two days. It looks nice, makes the car feel more roomy, and is the only option compatible with a roof rack or hooks you can install in the back to hang coats from (or whatever else you'd hang from the hooks in the back of most vehicles, but by default missing from the Tesla).
UHFS - I haven't heard the high fidelity option but the model I tested didn't have it and I wasn't impressed. Something was missing and that something seemed to be bass (along with some clarity). I've heard that the UHFS isn't spectacular either, but it's got to be better than the base!
Autopilot - absolutely. My current vehicle has it's version of TACC and I wouldn't want to drive a vehicle again without it. The Tesla version is already better than mine (BMW) and will be much cooler in a month or so. As others have also mentioned, other features could eventually come to the vehicle down the road to make it even better. The car will already likely be outdated in a few months, so I want to future proof as much as possible.
Premium interior - Are the extra lights worth $3000? I'm not sure. But the power lift gate is what sold me on this option. Very clever of Tesla to throw that into this package. You're already buying a very expensive car though and the package doesn't add that much to your monthly payments. Might as well throw it in! There are a few things I don't think any luxury car should be without and a power lift gate is one of them.
Smart air suspension - smoother ride, never know when you might need the extra height. That, and it's just kind of neat to show off. I went with it.
Next gen seats - I think they're a lot more comfortable than standard and look a lot more premium. If you're spending any significant time in the car, you'll be glad you got them. Upgraded seats are actually the one option I didn't get in my BMW and really wish I had!
