If you have the money, I would do the work ASAP. You won't feel different, performance-wise, from the water pump and belt. You may hear less noise from the timing tensioner, a bit.
If you want to car to run more smoothly, I would suggest doing a tune-up. You are close to your 120K mile mark. 120K miles service include, but not limited to, spark plugs (make sure that they are either NGK or Denso brand), wires, distributor cap and rotor, filters (air, fuel and PCV valve), and transmission service.
