Spark Plug Replacement

Alright Mopar guys, I'm sure you have answered this many a time. But, I have a 64 Dart /6 225. I want to get replace spark plugs, and I was looking at the NGK v-power part number 3459. If I replace the old ones, will I need to replace wires or anything like that? Any tips and tricks help. sorry I am kinda new to cars, alas I don't know everything. Thanks guys
