Driver memory seat
I can set my seat to recognize what key is unlocking the door to set the drivers seat to registered position (1, 2 or 3). Now when I customize settings in the Nav area so that the driver's seat slides back partially or fully when shutting down car, it no longer recognizes the keys. When I cancel the slide back option in the Nav, it quickly recognizes the keys again. I like both options and do wish that there is a way to remedy this. Is this normal?
I believe all personalized settings made via the NAV transfer identically to both key fobs equally. Thus, whatever personalized settings are made via the NAV will be the settings that will be provided to each driver regardless which of the two key fobs are used.
Make sure after you make your seat and steering wheel settings and memorize it to a particular seat number (Seat# 1, 2 or 3) that you then program the fob (for that particular driver's settings) to the same Seat number (1, 2 or 3). And, do the same thing for the settings for Driver #2, along with programming that fob to its particular seat setting.

Alright!! Alright!!! All these seems cool and all but what does the keyfob do anyway? 
So normally I got in my car and pressed my memory button and everything goes back to my preset settings. How does the keyfob memory work?

With your personal key fob you should be able to enter the car, put foot on brake and start the engine, and all your seat and steering wheel settings are automatically adjusted to your personalized and 'memorized' (to that particular fob) settings. And Driver #2 will have their seat and steering wheel settings automatically adjusted to their personalized and 'memorized' (to that particular fob) settings. Their should be no need to press Seat #1 or #2, etc. to adjust to your personalized settings after Driver #2 has driven the car 'if' you have programmed your fob to your particular seat position number.

If the service guy actually saved the settings (instead of just moving the seat/steering wheel without saving the settings), then your seat/steering wheel will be adjusted to 'his' newly set personalized settings when you start the car (if your key fob is programmed to the seat number you use - and he saved new positions into the memory). The service guy should not be 'saving' his preferred settings in your car, just adjusting them temporarily to suit his temporary needs.

Now how do I program my keyfob? I followed the video but when I press and hold my unlock button when the engine is off, my windows and sunroof open and I don't hear any beep. Is ours different than the one on the video?
With the GS 350 you need to press the 'door' unlock (or lock) switch, not the key fob's unlock button as the above video showed for another model.
With the GS 350: 'While pressing the recalled button, press and hold the door lock switch (either lock or unlock) until the buzzer sounds.'
Each individual Smart Key fob needs to be programmed separately with no other Smart Key nearby.
