Report will give you what you told it to. So whatever the function is every time it's called (iteration or timestep by default). It's another convergence monitor, but I'd only use the final value in most studies.
The Profile is single column text. It'll most likely be x, y & z positions and then whatever you told it to report. Again, it's what you asked for in that you wanted position v concentration data on that surface.
