Do I need to change brake fluid, clutch fluid and power steering fluid in my 2000 Honda ex 2Dr. coupe? It has 97,000 miles on it.

Unless you have a record of these fluids being changed in the past 18 months you should definitely change them. These fluids will degrade over time and need to be changed at appropriate intervals.
You should also flush the engine radiator and cooling system and replace with new coolant to the manufacturer's specs unless this has been done in the past 18 months.
Also ensure you change the engine oil and filter frequently (certainly more frequently than the manufacturer maximum interval specs which is based on optimum driving conditions which does not reflect reality.)

Frequent fluid changes = cheap preventative maintenance.

Brake fluid - every 2 years minimum
Clutch fluid - every 2 1/2 years minimum
PS fluid - every 3 years
Coolant flush and change - every 2 years
Engine oil - every 3500-4000 miles or 5 months minimum whichever is sooner
Oil filter - every second oil change.
