My Ford 2002 Ranger was running rough so I replaced the spark plugs. Now it is mis-firing badly. Should I have also changed the spart plug wires at the same time or is there simething else I should have done. The old set of spark plugs had at least 60K miles on them.

I would double check your plug wires. It is possible you crossed some of your wire's. At 60,000 it's not a bad ideal to replace them.
