4) Having the "auto" on the headlight is a bit confusing because I am used to the typical japanese cars (two clicks and headlights is on, now I have to do either 1 or 3 clicks). Haven't really look into the "auto" rain sensing wipers yet.
You know that the auto headlight means you leave it on the auto setting right? You don't need to keep turning to the off position every single time you get out of the car. The headlights stay on after you get out of the car at night for anywhere from 30-120 seconds. You can customize this under the settings
12) Got blind spot mirror and will be installing it tomorrow.
You don't need blind spot mirrors if you properly adjust the mirrors. The sides of the car should not be visible in your side mirrors. http://www.caranddriver.com/features/how-to-adjust-your-mirrors-to-avoid-blind-spots
14) Do all of you only have 2 keys from the dealer? My past cars I get 3 keys or more. 2 keys with keyfob and usually at least a valet key.
Only two keys. It's a smart key system, so there is no physical valet key as there is no keyhole to put it in.
21) When driving at night, the rear view mirror looking to the back seems very dark. Maybe because I am not used to tinted rear
You have an auto-dimming mirror. It darkens when there are lights behind you so you aren't blinded.
22) May I ask what is the point of that P/R/N/D thing going down like a maze? It's not a stick shift just make it plain and simple. Just up and down is fine. I think it's just dumb. Maybe it's me.
There are many cars that use this setup. Lexus, Mercedes, Toyota... I actually prefer it over a straight back setup as you don't have to depress a button to change positions. Also, it allows a physical manual mode instead of stupid shift buttons like GM and Ford uses.
