Having problems with your 1996 GMC Suburban ?

Engine misfiring. I have a 1996 GMC Suburban with a 454 ci engine and 235,000 miles. The misfiring started a month ago, I have replaced the plugs (ACDelco Set at 0.035), the Spark Plug Wires (2yrs old/15,000 miles on them) look to be in goog shape My next move is to replace the rotor and cap. Question: Am I correct on the gap for the plugs? What is the firing Order? Where is number one on the distributor cap? Should I replace the wires again?
