Good Write Up. I would have loved to find something like this as I started my wait. One thing you might mention is the My Tesla page and specifically the "Please complete the following tasks to prepare for your Tesla delivery".
When I saw bright red "!" indicators next to payment and trade-in, I jumped right on those missing items only to find out I was too early.Financing approval is only valid for 30 days, so you should wait at least until your car is in production to apply. Otherwise you'll just have to repeat the process later. And I thought something was wrong when it just said "preparing offer" next to trade-in, so I followed up to get an offer only to learn that it is only valid for 7 days. The My Tesla page says complete everything within 14 days of receiving the offer, but I was told 7 is the current magic number. Feels a bit weird for Tesla to highlight items that don't need attention yet, but that appears to be the case.
Another point that might be worth making is that Tesla will send emails as the car moves through the process but you can often see progress on the My Tesla page before the email arrives. And it is a great resource for those who do not get an email. As an example, your VIN will appear next to "Model S" right below the picture of the car. There have been a few threads where that appeared not to be well known. For those who haven't received an email and are wondering if something is wrong, you can go to the web and see your car's VIN and know if it has been assigned.
And most likely know this, but you could also add in a link to the charger and a note that there is often a 1-2 week delay.
Great job.
