Thanks Guys for the info.
Mark, no the flange is not in place. When they built our house, they just roughed the plumbing to the location where the toilet will sit. I had to break/chip away some of the concrete to get down to the elbow. I have a piece of pipe that needs to be adhered to that elbow, and then cut to the proper length to match up with the flange. I'm planning now on tiling around the pipe, just below the flange, so the flange will be on top of the tile, and then put the wax ring centered on top of that.....fun fun fun
