where tiled wall meets tiled shower floor

hello and help!
We've got the Kerdi membrane installed over the newly built shower stall. The quarter inch thick tumbled porcelain 4"x4" + 6"x6" tiles have been installed with Mapei Kerabond/Keralastic. We're ready to grout (we have the Mapei ultracolor grout).
It seems that the seam where the tiled walls meet the tiled 30" x 40" floor is to be caulked rather than grouted. iIve also read that it should be first grouted, then topped with caulk! What's the real scoop?
The seam varies slightly in size, but with the thick tiles resting on the Kerabond base,there are definitely places where I can insert my pinkie in, at least a half-inch, right to the Kerdi membrane -- this is not a hairline joint! So, do I pack in caulking along the four wall/floor edges, filling that void completely with caulk? If so, how long to dry? Any preferred type of caulk, or ones to avoid? I have the Mapei latex, but have read that silicone is what should be used....Also, do I first grout the stall walls and floor, then caulk the floor/wall joints, so the caulking has a dry surface to grip, or does the order not matter?
Thanks!! Your website convinced me to go with the Schluter system. Now I just want to make sure it's done right!
