They're needed for VHF/UHF Mot systems on the PRO-96 if the system has more than one "table entry". The PRO-97 doesn't support multiple table entries.

2. Do channel numbers correspond to a specific frequency?

Within the context of that table entry, yes:
Code:
if ( chan >= LoChan && chan <= HiChan )
VoiceFreq = Base + Step * (chan - Offset);
<chan> = channel number received in "call grant" message

3. Motorola UHF Trunked systems require Base, Step & Offset data to properly monitor the system. I understand the Step function however can you provide some information on Base and Offset or suggest another site where this information can be found?

See the formula above. Base, Step, and Offset are all used to calculate a voice frequency when given a "channel number" from the control channel's "call grant" message.
