Paul, please keep all your project questions on one thread so folks can see what you're working on and what's been previously asked and answered. A moderator can give it a more generic title any time you'd like to suggest one.

See Post #9.

The required slope is a minimum requirement. You would make your perimeter of the pre-slope (again we're assuming you intend to build a traditional shower receptor) level all the way around at the level of the maximum height. In your case that would be a minimum of 1" higher than the top of the bottom portion of your clamping drain. A bit higher is better to be sure you meet the minimum requirement. The slope will be different in the other quadrants of your receptor because of the drain location.

I would recommend as your first step that you center the drain in the shower footprint.

My opinion; worth price charged.
