Take a deep breath (lol)... slow down just a bit. First, read through that manual that I linked for you in the other thread you started, probably a couple times. There is a lot to learn, but the tesla manual has a ton of really good information in there.
I will take a stab at some of your questions but remember you are asking some things that are opinions.
1. Should I change the software update to advanced?
A. Thats a personal choice that no one is even sure makes any difference in the frequency of updates. Given how new the car is to you, I would suggest you leave it set however it is, and proceed with reading the manual first before worrying about software update settings.
2. Do I turn on Pin to drive in Safety settings?
A. Up to you, since it sounds like you dont have a garage, many people in that situation turn it on. Its kind of like asking "should i lock my garage door?" or something. Depends on your personal circumstances, desire, etc. It wont hurt anything, but will make getting the car going every day have an additional step.
3.Does my wife need her own account or can she use mine?
A. Its possible to share an account, and its also possible to have multiple people have their own accounts and drive the car. You can read through this thread / explanation I created on the topic. Its out of date as far as steps, as right now, you add additional drivers using the tesla app, but the information will get you started:

4. Do I use sentry mode?
A. Probably not, because from your other post you dont have home charging and are unsure how to charge your car. Sentry mode will use approximately 1-2 miles of range PER HOUR, just sitting there, because your car will not sleep. Roughly 20-30 miles lost PER DAY. The very people who think they want to use sentry mode all the time (those that park outside without home charging), are the people who shouldnt use it unless they have access to charging somewhere else.
5. What comes with premium connectivity?
A. See the tesla website here for the subject
Connectivity is an important part of all Tesla vehicles, further enhancing the driving experience by providing access to features that require data usage. Find out more about Standard and Premium Connectivity.
