What does Z 1 DS 0023 32bit 0(FFFFFFFF) mean?
I don't have any experience with ollydbg, but I can tell you without a doubt that the Z stands for the zero flag and DS 0023 is the value in the DS (data segment) register. I don't know what the rest means exactly. I think it's information about the memory address at that segment.
You should look at that set of information as two columns of register/value pairs. The first column are the various status flags, the next for the segment registers.
