Default New bluestone patio, 1st step, literally

Hello all, I am about to embark on my 3rd DIY patio install but have a question about a granite step. The patio will be two steps below the entrance to the house and I want to use a 36"x7"x 6' pad for the step. The quarrie told me the granite will weigh in at 1700lbs, and that if i do not want it to settle, I should pour a proper footing and foundation. Well, as luck would have it, the house is built directly on ledge, so I do not need a footing, just a foundation.

I plan to build a cinderblock wall and pin it to the ledge. This wall will be 5 feet wide and about 30 inches out from the house foundations (about 6 inches smaller than the granit step).

Question is, what size rebar should I use to pin the blocks? 1/2 inch, or heavier?

Should I build a 3rd wall from the house foundation wall to the front of the foundation in the middle of the outerwalls? I am not sure if I need additional support for the step in the middle. I plan to fill the foundation with soil so it won't heave over time.

What slope should I build for the top course? I think 1/4 inch per foot is too steep (3/4 inch total). Maybe just 1/4 inch overall?

Last, and the biggie, how would I move this monster block. It is clearly too big for my BX23. Maybe fork lift bars on a bobcat or something? Not sure about how to do this just yet, so suggestions would be appreciated.
