You'll most likely just want the output frequencies. What you're seeing listed are repeaters. The take the signal from lower power mobile radios on the input frequency and repeat/retransmit them on the output to extend their range.
The input is what users transmit on and the output is what they listen to. PL tone is a subaudible tone that is transmitted along w/ the voice to help prevent interference(the radios on the system will ignore anything w/o the tone).
