Yeah, the naming gets really confusing. If I'm reading it correctly, you're right, "c" and "d" are the ones you need. The picture you showed should be "d". "C" will help correct the transmission sitting on the crossmember. Mine was within 1/8 of an inch when I replaced it, and it now has probably 3/4 of an inch clearance.
I can't help with the SVT questions. I have a zetec mtx, and I replaced mine with the stock Ford mounts. I recall that there have been some previous discussions about using SVT roll restrictors on non-SVT cars.
