Dry rock on the bottom with the live rock on top. You can add the base rock before water, that would make it easier to move around. Add rock before sand to prevent shifting when critters move the sand out from under the rock. Add live rock after water. I wonder how much of the life on the tampa bay rock would survive a cycle? Also, the rock you picked looks to be very dense. As others have said porous rock is better for housing bacteria. I personally like the Pukani from BRS, you get a lot of rock (volume) for your money. Down side is the trapped nutrients (several ways to address this, all discussed at length on this site). I cycled/cured mine in a Brute with water changes using the water from my aquarium water changes.
