1996 Honda Civic Do I need a water pump?

I bought my car in July 2007 with 100,000 miles. I'm pretty sure it has the original timing belt so I'm actually deciding to fix something before it's broken this time.

I'm going to get a new belt but do I need a water pump? When the mechanic was taking the belt apart he said he saw an small "orange, goopy" leak near where the pump connects to the motor but besides that the pump looked ok.

Thanks.
