Grand Canyon- Proper Sunset exposure with Graduated ND Filter

I plan shortly to visit the Grand Canyon.

I plan to shoot sunrise and sunsets with a Graduated ND Lee filter.

My equipment:

Silk Graphite tripod with RRS ball

Canon M50 Mark ll

Lenses:

Canon EF-M 15mm-45mm

Canon EF-M 55mm-200mm

Adapter for:

Canon EFS 110-22mm

Tamron Piezo Drive VC 16-300mm

Filters:

LEE 100x150mm 0.6 Grad ND

Lee 100 x 150mm Grad ND

Lee 100 Sunset 2

Lee 100 Big Stopper

Lee 100 Little Stopper

B&W Circular PL for all lens

My question if using the EF-m 55-200 or EFS 10-22

If I shoot with AV setting, F9 or F11, ISO 100, and use both the O.6 and 0.9 Grad ND, this should change my exposure by 5 stops (2 more stops if a Circular Polarizer is used).

In the scenario given :

1- what is the correct method to find the right exposure?  Use the histogram and change the exposure until proper?

2- Is there a way to lock automatic focus, or should I manually do it? I like spot metering, and touching my LED screen to set the focus.

3-When is the proper time to focus?

Thanks so much in advance for the anticipated response.  I am an amateur who reads a lot.  Do not want to mess up my opportunity for some great shots.
