If you gap all the new plugs first and then replace the plugs and wires one at a time you won't have to worry about messing up the firing order. (This will happen if you pull all the plug wires at once and don't replace them in the same locations.)
coil pack bad, or wires could be faulty/old should replace them, or the sparkplug itself could be bad try replacing plugs & wires and start from there

No, they don't necessarily have to be replaced. However it is usually a good idea to replace the wires along with the spark plugs. As the wires age and go through heating cooling cycles they get stiff and brittle. As you flex the wires to remove them from the spark plugs the inner conductor often breaks causing a misfire. Also when you pull the spark plug boots off of the spark plugs the connector often can break loose and stay on the spark plug, thus ruining the wire.
